board: arm: Enable MPU for all STM32 boards supporting it

Browse source 
Only boards with at least 64K Flash will activate MPU because:
MPU + UERSPACE + All switches implicity activated
(CONFIG_MPU_STACK_GUARD, CONFIG_ARM_STACK_PROTECTION ...)
will consume about 40K Flash
(value computed on nucleo_f767_zi on tests/arch/arm/arm_ramfunc/).
