The GPIO driver for the Intel Apollo Lake has so many pins it has to
export ten devices to shoehorn its one device into the GPIO API. The
current implementation uses the shared IRQ driver because these
pseudodevices all share one IRQ. However, since the GPIO driver is
aware of all the possible interrupt sources, it's smaller and faster
(and not even messy) to handle it internally, so this patch eliminates
the dependency on the shared IRQ driver.

Same deal as in commit 4638652214 ("Kconfig: Use 'default' instead of
'def_bool' in Kconfig.defconfig files"), fixing new stuff that got
introduced since then.
Some symbols, like ALTERA_AVALON_PIO, are only defined in
Kconfig.defconfig files, and so need the def_bool.
Motivation (from the note at the end of
guides/kconfig/index.html#common-shorthands):
For a symbol defined in multiple locations (e.g., in a Kconfig.defconfig
file in Zephyr), it is best to only give the symbol type for the "base"
definition of the symbol, and to use 'default' (instead of 'def_<type>'
value) for the remaining definitions. That way, if the base definition
of the symbol is removed, the symbol ends up without a type, which
generates a warning that points to the other definitions. That makes the
extra definitions easier to discover and remove.

A parallel PCI implementation ("pcie") is added with features for PCIe.
In particular, message-signaled interrupts (MSI) are supported, which
are essential to the use of any non-trivial PCIe device.
The NS16550 UART driver is modified to use pcie.
pcie is a complete replacement for the old PCI support ("pci"). It is
smaller, by an order of magnitude, and cleaner. Both pci and pcie can
(and do) coexist in the same builds, but the intent is to rework any
existing drivers that depend on pci and ultimately remove pci entirely.
This patch is large, but things in mirror are smaller than they appear.
Most of the modified files are configuration-related, and are changed
only slightly to accommodate the modified UART driver.
Deficiencies:
64-bit support is minimal. The code works fine with 64-bit capable
devices, but will not cooperate with MMIO regions (or MSI targets) that
have high bits set. This is not needed on any current boards, and is
unlikely to be needed in the future. Only superficial changes would
be required if we change our minds.
The method specifying PCI endpoints in devicetree is somewhat kludgey.
The "right" way would be to hang PCI devices off a topological tree;
while this would be more aesthetically pleasing, I don't think it's
worth the effort, given our non-standard use of devicetree.

The i2s_cavs.c driver manipulates cache lines before commencing
any DMA transfers. With write-back cache, if the DMA receive
buffer is not aligned to the cache lines, the data around
the buffer will be invalidated and may never written to memory.
Since the driver takes an external memory slab as buffer and
there is no easy way to force cache line alignment on
the application side, set the cached region to write-through
to avoid potential issue.

Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

This macro is slated for complete removal, as it's not possible
on arches with an MPU stack guard to know the true buffer bounds
without also knowing the runtime state of its associated thread.
As removing this completely would be invasive to where we are
in the 1.14 release, demote to a private kernel Z_ API instead.
The current way that the macro is being used internally will
not cause any undue harm, we just don't want any external code
depending on it.
The final work to remove this (and overhaul stack specification in
general) will take place in 1.15 in the context of #14269Fixes: #14766

There exists SoCs, e.g. STM32L4, where one of the low power modes
reduces CPU frequency and supply voltage but does not stop the CPU. Such
power modes are currently not supported by Zephyr.
To facilitate adding support for such class of power modes in the future
and to ensure the naming convention makes it clear that the currently
supported power modes stop the CPU this commit renames Low Power States
to Slep States and updates the documentation.

Since commit 0906a51dac, the driver
fails the test: tests/drivers/adc/adc_api. Some of the workflow
turns out to be incorrect (e.g. not doing dummy conversion after
getting out of deep power down, and not clearing interrupt status
bits). So take some time to overhaul the driver. Also rename
the driver to adc_intel_quark_se_c1000_ss because the inner
working of this driver is tied to Quark SE C1000 SoC.
