ARM: mpu: add PMSA related registers and bitfields to existing headers
This patch adds the following definitions relevant to the PMSA:
Add SCTLR bit 17, (CR_BR - Background Region bit) to the list of CR_*
bitfields. This bit determines whether to use the architecturally defined
memory map
Add the MPUIR to the available registers when using read_cpuid macro. The
MPUIR is the MPU type register.
