What is the change?
- PXN attributes is set for static mpu regions such that
__ramfunc and __ram_text_reloc having userspace code
cannot be executed in privileged mode.
- Updated the notable change section to inform about the change in
behaviour of code executed from __ramfunc and __ram_text_reloc MPU
regions.
Why do we need this change?
- The current static MPU regions allows executing userspace/unprivileged
code from privileged mode which may not be expected and can lead to
secure privileged escalation attacks.

What is the change?
This commit adds support for Armv8.1-M MPU architecture's PXN attribute.
This includes support for configuring MPU regions with PXN via
custom mpu_config, devicetree and static mpu_config.
The existing MPU region attribute macros are updated to retain existing
behaviour with this change with an addition of REGION_RAM_ATTR_PXN to be
used if one needs to configure a RAM region with PXN MPU attribute.
Why do we need this change?
Armv8.1-M architecture introduced a new MPU region attribute called
Privilege eXecute Never (PXN).
If an MPU region is configured with the PXN attribute set and if the,
processor attempts to execute code in this region while at
privileged level, a Memory Management Fault exception is triggered.
This ensures that specific tasks are executed only in unprivileged mode
and helps in preventing secure privilege escalation attacks.

This commit workarounds the BBRAM status register write issue in npcx4:
A write operation to the BKUP_STS register might disable write to all
the Battery-Backed RAM (BBRM). The workaround is to perform a fake read
from the BKUP_STS register after every write to this register.
