Based on the definition of _ARCH_THREAD_STACK_DEFINE() macro
for ARM, the MPU Stack Guard region is placed inside the
allocated stack object, only if
CONFIG_MPU_REQUIRES_POWER_OF_TWO_ALIGNMENT and CONFIG_USERSPACE
are both set. For ARM stack objects, allocated using the
_ARCH_THREAD_STACK_DEFINE() macro, such as the threads' stacks
and the interrupt stack, the above must be reflected on how we
set the initial start of the stacks.
