We need to use CPUAPP and CPUNET instead of CPU0 and CPU1
terminology, because those terms are the ones used
throughout the DeviceTree definitions for nRF5340 SoC.

Move the definition of the number of MPU regions
(num-mpu-regions) in a SoC variant-specific header
instead of the common .dtsi for nRF5340 Application
MCU. This allows us to define different SoC variants
with different number of MPU regions available.
