STM32L1 uses the same spi controller as STM32F1 so we can just set the
right addresses and enable them. We also need to add the fixup names and
to correctly include the header for ST LL HAL.

1. Replace the non-existent CPU device binding ("Cortex-R") specified
by the CPU node with a proper one.
2. Relocate CPU node declaration to SoC dtsi:
The CPU node should be declared in the SoC dtsi because the core
type is SoC-dependent. In fact, this is exactly how it is done in
the Cortex-M port.
3. Remove core_intc (supposedly Cortex-R VIC):
Unlike the NVIC of Cortex-M, the VIC of Cortex-R is not a true
interrupt controller in the conventional sense and merely acts as
a CPU input port for aggregated interrupt request and vector index
signals. For this reason, there is no point in declaring it in the
device tree and specifying it as an interrupt parent. All SoCs
incorporating Cortex-R implement a separate true interrupt
controller (for instance, GIC for Zynq MPSoC and VIM for Hercules).

Looking at the code, this flag was probably made 'required: true' by
mistake. Combining 'type: boolean' with 'required: true' for 'ppi-wrap'
means that all nodes that use this binding are required to have a
'ppi-wrap;' property.
The mistake was hidden by a bug in edtlib (failing to flag missing
'required: true' booleans).

Implement a nice generalization suggested by Bobby Noelte.
Instead of having a generic #cells key in bindings, have source-specific
*-cells keys. Some examples:
interrupt-cells:
- irq
- priority
- flags
gpio-cells:
- pin
- flags
pwm-cells:
- channel
- period
This makes bindings a bit easier to read, and allows a node to be a
controller for many different 'phandle-array' properties.
The prefix before *-cells is derived from the property name, meaning
there's no fixed set of *-cells keys. This is possible because of the
earlier 'phandle-array' generalization.
The older #cells key is supported for backwards compatibility, but
generates a deprecation warning.

Generating generic information for 'type: phandle-array' properties in
edtlib was difficult due to defining phandle-array as just a list of
phandles and numbers. To make sense of a phandle-array property like
'pwms', you have to know that #pwm-cells is expected to appear on
each referenced controller, and that the binding for the controller has
a #cells.
Because of this, handling of various 'type: phandle-array' properties
was previously hardcoded in edtlib and exposed through properties like
Node.pwms, instead of through the generic Node.props (though with a lot
of shared code).
In practice, it turns out that all 'type: phandle-array' properties in
Zephyr work exactly the same way: They all have names that end in -s,
the 's' is removed to derive the name of related properties, and they
all look up #cells in the binding for the controller, which gives names
to the data values.
Strengthen the definition of 'type: phandle-array' to mean a property
that works exactly like the existing phandle-array properties (which
also means requiring that the name ends in -s). This removes a ton of
hardcoding from edtlib and allows new 'type: phandle-array' properties
to be added without making any code changes.
If we ever need a property type that's a list of phandles and numbers
but that doesn't follow this scheme, then we could add a separate type
for it. We should check if the standard scheme is fine first though.
The only property type for which no information is generated is now
'compound'.
There's some inconsistency in how we generate identifiers for clocks
compared to other 'type: phandle-array' properties, so keep
special-casing them for now in gen_defines.py (see the comment in
write_clocks()).
This change also enabled a bunch of other simplifications, like reusing
the ControllerAndData class for interrupts.
Piggyback generalization of *-map properties so that they work for any
phandle-array properties. It's now possible to have things like
'io-channel-map', if you need to.

This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.
Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:
* dts/bindings/spi/
new binding for "nordic,nrf-spim" is added and common fields for all
3 types of Nordic SPI peripherals are extracted to a shared file
* dts/arm/nordic/
"compatible" properties in spiX nodes are updated (when there is no
choice as only one type of SPI peripheral is available) or replaced
with a comment pointing out that the proper type of peripheral needs
to be picked at some upper layer
* drivers/spi/
spi_nrfx_spim driver is updated with the new form of macros generated
from dts
* boards/

updated with the proper "compatible" property, according to the type
of SPI peripheral that is currently selected for the board by the
corresponding Kconfig choice option (SPI_x_NRF_SPI*)

Add support for up-and-down counter mode, which aligns the center of
each channel's pulses instead of their initial edges. This is enabled
on a PWM periphral by adding the "center-aligned" property to the
device tree, e.g.:
&pwm0 {
status = "okay";
center-aligned;
ch0-pin = <15>;
ch1-pin = <17>;
ch1-inverted;
};

Deprecate 'sub-node:' and add a more general 'child-binding:' mechanism
to bindings. Keep supporting 'sub-node:', but print a deprecation
warning when it's used.
Like 'sub-node:', 'child-binding:' gives a binding to child nodes, but
the binding is required to be a complete binding, and is treated (and
checked) like a normal binding.
'child-binding:' can in turn contain another 'child-binding:', up to any
number of levels. This is automatic from treating it like a normal
binding, and from the code initializing parent Devices before child
Devices.
This lets nodes give bindings to grandchildren.
For example, take this devicetree fragment:
parent {
compatible = "foo";
child-1 {
grandchild-1 {
...
};
grandchild-2 {
...
};
};
child-2 {
grandchild-3 {
...
};
};
};
The binding for 'foo' could provide bindings for grandchild-1/2/3 like
this:
compatible: "foo"
# Binding for children
child-binding:
title: ...
description: ...
...
# Binding for grandchildren
child-binding:
title: ...
description: ...
properties:
...
Due to implementation issues with the old devicetree scripts, only two
levels of 'child-binding:' is supported for now. This limitation will go
away in Zephyr 2.2.
Piggyback shortening 'description:' and 'title:' in some bindings that
provide child bindings. This makes the generated header a bit neater.

The arc_iot.dtsi used "intel,qmsi-ss-gpio" and "intel,qmsi-ss-i2c"
compatiables, however we have no drivers for these and it seems wrong
that the ARC platform would utilize such compatiables. Remove the
compatiable fields for now (proper one's can be added when there are I2C
and GPIO drivers for this platform).
Also remove the binding files associated with "intel,qmsi-ss-gpio" and
"intel,qmsi-ss-i2c" as nothing in tree utilizes them.
