Ioannis Glaropoulos 9b03cd8bdc arch: arm: allow user to fall-back to MPU-based guards in ARMv8-M
ARMv8-M architecture supports the built-in stack overflow
detection mechanisms via the SPLIM registers. However, the
user might still wish to use the traditional MPU-based stack
overflow detection mechanism (for testing or other reasons).
We now allow the user to enable HW stack protection, but
manually turn off BUILTIN_STACK_GUARD option. This will force
the MPU_STACK_GUARD option to be selected.

It is still not allowed for the user to not select any stack
guard mechanisms, if HW_STACK_PROTECTION is selected.
