The STM32F7 uses the same USB OTG FS controller than the STM32F4 series.
It is therefore trivial to add support for it, by adding the DT fixup
and pinmux macros, and the DT entries in stm32f7.dtsi. Keep it disabled,
it should be enabled at the board level.

Update _get_region_attr_by_type used to set up the user regions
on a per thread basis to match the REGION_USER_RAM_ATTR macro. Caching
attributes were set "Outer and inner write-through. No write allocate.",
this patch changes it to "Outer and inner write-back. Write and read

Reduces the number of mpu regions statically reserved at boot time by
one, giving a total of five. We originally sought to reduce the total to
three: 1 background region with lowest precendence for supervisor r/w, 1
flash region, and 1 sram region. However, the nxp mpu hardware does not
give precedence to any region over another, and thus we cannot revoke
access from the background region with a higher priority region. This
means we cannot support hardware stack protection with a single
background region.
Instead, create two background regions that cover the entire address
space, except for sram.

This commit refactors internal functions in arm_mpu.c to use
bitsets and functions taken directly from ARM CMSIS instead of
hardcoded arithmetic literals. In several internal functions
some part of the implementation is abstracted further in inline
functions or convenience macros, to facilitate extending the
arm_mpu.c for ARMv8-M. In addition, the commit adds minor
improvements in internal function documentation.

This commit abstracts the attribution generation for an MPU

This commit places all the implementation in arm_mpu.c within
build-time guards, ensuring that it is compiled-in only if the
kernel features requiring MPU are present (i.e. USERSPACE,
APPLICATION_MEMORY, or MPU_STACK_GUARDS). An exception to that
is the code required for MPU initialization, which is left out,
as MPU initialization occurs always if MPU is present.

This commit adds an explanatory comment in all soc.h headers,
where kernel_includes.h header has been included, to stress out

SOC-specific header inclusions.

* We are now *much* better at not reserving unnecessary
system MPU regions based on configuration. The #defines
for intent are now an enumerated type. As a bonus, the
implementation of _get_region_index_by_type() is much
simpler. Previously we were wasting regions for stack guard
and application memory if they were not configured.
* NXP MPU doesn't reserve the last region if HW stack
protection isn't enabled.
* Certain parts of the MPU code are now properly ifdef'd
based on configuration.
* THREAD_STACK_REGION and THREAD_STACK_USER_REGION was a
confusing construction and has now been replaced with
just THREAD_STACK_REGION, which represents the MPU region
for a user mode thread stack. Supervisor mode stacks
do not require an MPU region.
* The bounds of CONFIG_APPLICATION_MEMORY never changes
and we just do it once during initialization instead of
every context switch.
* Assertions have been added to catch out-of-bounds cases.
