PSoC-6 SoC needs that user define the nvic interrupt number to bind
with the peripheral interrupt line for the Cortex-M0+ CPU. It uses
a multiplex before any NVIC interrupt line. The interrupt vector is
selected using interrupt-parent property with the intmux_chN number
reference.
Note: The PSoC-6 SoC allows that both CPUs receive the same interrupt.
A tipical use is GPIO interrupt handle and user is responsable to
define interrupt line, priority and take care of enable same peripheral
instance on both CPUs only when appropriated.

This emulator pretends a generic eSPI Host. It supports basic virtual
wires and port80 operations.
There are functions to trigger actions on the host side e.g. for
setting a virtual wire from the host to the eSPI slave, use
emul_espi_host_send_vw. It will prepare data and set a proper event
on the slave side which will trigger callback (if there is any).

Add an emulation controller which routes eSPI traffic to attached
emulators depending on the selected chip(mostly host).
This allows drivers for eSPI peripherals to be tested on systems
that don't have that peripheral attached, with the emulator handling
the eSPI traffic.

This adds the correct compiler and linker flags to
support software floating point operations. The flags
need to be added to TOOLCHAIN_*_FLAGS for GCC to find
the correct library (when calling GCC with
--print-libgcc-file-name).
Note that software floating point needs to be turned
on for Newlib. This is due to Newlib having floating
point numbers in its various printf() functions which
results in floating point instructions being emitted
from toolchain. These instructions are placed very
early in the functions which results in them being
executed even though the format string contains
no floating point conversions. Without using CONFIG_FPU
to enable hardware floating point support, any calls to
printf() like functions will result in exceptions
complaining FPU is not available. Although forcing
CONFIG_FPU=y with newlib is an option, and because
the OS doesn't know which threads would call these
printf() functions, Zephyr has to assume all threads
are using FPU and thus incurring performance penalty as
every context switching now needs to save FPU registers.
A compromise here is to use soft float instead. Newlib
with soft float enabled does not have floating point
instructions and yet can still support its printf()
like functions.

The changes here are the result of running all open pull-requests
through a script to identify the assignee and findi ng many gaps or old
data. Some of the changes here are coming from pending PRs that were
waiting for some TSC confirm ation, others are done based on pending
maintainer and collaborator changes that were not submitting yet.
Two noteable changes:
- CMake/Build system: This is now limited to just the infrastructure and
not every single Cmake file in the tree. - Documentation: ditto, this
is just for the doc infrastructure and not for every RST file in the
tree.
The reason for the above two changes is the fact that most PRs would
have some cmake or doc changes and assignees in this case should not be
the owners of the build system or the doc infra, instead we should
assign to the subsystem being changed. (Otherwise majority of PRs would
be assigned to the doc and build system maintainers).

Linking with newlib now defines the following linker flags as:
```
${CMAKE_C_LINKER_WRAPPER_FLAG}${CMAKE_LINK_LIBRARY_FLAG}c
${CMAKE_C_LINKER_WRAPPER_FLAG}${CMAKE_LINK_LIBRARY_FLAG}gcc
c
```
This is needed because when linking with newlib on aarch64, then libgcc
has a link dependency to libc (strchr), but libc also has dependencies
to libgcc.
CMake is capable of handling circular link dependencies for CMake
defined static libraries, which can be further controlled using
`LINK_INTERFACE_MULTIPLICITY`.
However, libc and libgcc are not regular CMake libraries, and is seen as
linker flags by CMake, and thus symbol de-duplications will be
performed.
CMake link options cannot be used, as that will place those libs first
on the linker invocation. -Wl,--start-group is problematic as the
placement of -lc and -lgcc is not guaranteed in case later libraries are
also using -lc / -libbgcc as interface linker flags.
Thus, we resort to use
`${CMAKE_C_LINKER_WRAPPER_FLAG}${CMAKE_LINK_LIBRARY_FLAG}`
as this ensures the uniqueness and thus avoids symbol de-duplication
which means libc will be followed by libgcc, which is finally followed
by libc again.
It would have been possible to use `-lc` directly, but there is a risk
that an externally library is also adding `-lc` and thus de-duplication
and re-arrangement of this flag happens. This risk is in theory also
existing with this fix, but the long nature of this link flag with using
`${CMAKE_C_LINKER_WRAPPER_FLAG}` would likely indicate a similar fix and
thus those libraries will stay in order.

Currently configuration for STM32F746G Discovery board on reset-start
event is inherited from included files (OpenOCD stm32f7x.cfg), but
contrary to the inherited adapter speed on reset-init event, the speed
inherited for the reset-start event is only 2000 kHz, which is not
available, so a lower speed is picked up automatically generating the
following message several times when flashing the board:
Info : Unable to match requested speed 2000 kHz, using 1800 kHz
That commit overrides that suboptimal speed for reset-start event and
sets it to the same speed as used by reset-init event, i.e. the maximum
speed (4000 kHz), so the noisy messages like the above one disappear.
The change also improves a bit the throughput when writing to the board.
