for I2C peripherals to be tested on systems that don't have that

Create a header file and implementation for emulators. Set up a linker
list so that emulators can be found and initialised at start-up.
Emulators are used to emulate hardware devices, to support testing of
various subsystems. For example, it is possible to write an emulator
for an I2C compass such that it appears on the I2C bus and can be used
just like a real hardware device.
Emulators often implement special features for testing. For example a
compass may support returning bogus data if the I2C bus speed is too
high, or may return invalid measurements if calibration has not yet
been completed. This allows for testing that high-level code can
handle these situations correctly. Test coverage can therefore
approach 100% if all failure conditions are emulated.

To debug hard-to-reproduce faults/panics, it's helpful to get the full
register state at the time a fault occurred. This enables recovering
full backtraces and the state of local variables at the time of a
crash.
This PR introduces a new Kconfig option, CONFIG_EXTRA_EXCEPTION_INFO,
to facilitate this use case. The option enables the capturing of the
callee-saved register state (r4-r11 & exc_return) during a fault. The
info is forwarded to `k_sys_fatal_error_handler` in the z_arch_esf_t
parameter. From there, the data can be saved for post-mortem analysis.
To test the functionality a new unit test was added to
tests/arch/arm_interrupt which verifies the register contents passed
in the argument match the state leading up to a crash.

This patch adds support for the Texas Instruments LP5030 and LP5036
I2C LED controllers. They are respectively providing up to 30 and 36
channels (i.e. 10 or 12 RGB LEDs).
In addition to the channel/color registers this LED controller provides
a per-LED brigthness register. This driver implements both LED-based and
channel-based API methods:
- led_on
- led_off
- led_get_info
- led_set_brightness
- led_set_color
- led_set_channel
- led_write_channels

Some LED controllers are connected to a large number of LEDs (i.e.
array/strip of LEDs). A user may need to set several LEDs at the same
time. The LED oriented syscalls are not adapted to this task. Indeed a
call per LED is needed to configure a group of LEDs. To that end, this
patch adds the led_set_channel and led_write_channels syscalls to the
LED API. They offer direct access to the raw channels. They respectively
allow to set a single channel and to write several contiguous channels
(and therefore to configure a group of LEDs).
Moreover the addition of the led_write_channels syscall also aims at
closing the gap with the LED strip API.

For the LED controller without any hardware blinking capability this
doesn't really make sense to make the blink callback mandatory. It is
better to let it undefined. This way this will allow the LED API to
fall back to a common software blink implementation.
In addition some controllers with RGB LEDs don't have the capability
to configure the LED brightness but only the channel/color levels.
Their drivers may only implement the set_color callback.
That's why this patch makes the blink and set_brightness LED API
callbacks optional.

The led_set_color syscall adds support for multicolor (i.e.
multi-channel) LEDs to the LED API. It allows a user to set all the
colors/channels of a LED at once by passing a color array. Note that
this array must provide an entry per color/channel and must also be
ordered following the color mapping of the LED. This color mapping can
be either retrieved from the "color-mapping" DT property or from the LED
driver itself (by using the led_get_info syscall).
Signed-off-by: Simon Guinot <simon.guinot@seagate.com>
When supported by the driver the led_get_info syscall allows a user
to retrieve the following information about each LED available:

- The number of colors/channels.
- And for a multicolor LED a pointer to a channel-color mapping.

Actually the LED API functions are handling channel objects. The "led"
parameter passed to the functions is defined as a channel number. This
patch redefines it as a LED number instead.
Note that this patch doesn't change anything for the drivers handling
mono-color (or single channel) LEDs. For the drivers handling multicolor
(or multi-channel) LEDs, such as the lp5562, then the API is broken.

Most if not all drivers use an internal function
spi_context_configured() to bypass reconfiguring the SPI peripheral
when nothing has changed. That function determines change based on

The x86 paging code has been rewritten to support another paging mode
and non-identity virtual mappings.
- Paging code now uses an array of paging level characteristics and
walks tables using for loops. This is opposed to having different
functions for every paging level and lots of #ifdefs. The code is
now more concise and adding new paging modes should be trivial.
- We now support 32-bit, PAE, and IA-32e page tables.
- The page tables created by gen_mmu.py are now installed at early
boot. There are no longer separate "flat" page tables. These tables
are mutable at any time.
- The x86_mmu code now has a private header. Many definitions that did
not need to be in public scope have been moved out of mmustructs.h
and either placed in the C file or in the private header.
- Improvements to dumping page table information, with the physical
mapping and flags all shown
- arch_mem_map() implemented
- x86 userspace/memory domain code ported to use the new
infrastructure.
- add logic for physical -> virtual instruction pointer transition,
including cleaning up identity mappings after this takes place.
