[PATCH 00/11] Add Cortex-R52

[Tobias Roehmel <quic_trohmel@quicinc.com>]

These patches add the ARM Cortex-R52. The biggest addition is
an implementation of the armv8-r MPU.
The last patch adds a machine that combines the new core with
an UART and a GIC. This machine can run many samples of
the Zephyr OS.

All information is taken from:
- ARM Cortex-R52 TRM revision r1p3
- ARM Architecture Reference Manual Supplement
    -ARMv8 for the ARMv8-R AArch32 architecture profile Version A.c

Functionality that is not implemented:
- Changing between single and double precision floats
- Some hypervisor related functionality (HCR.T(R)VM,HADFSR,...)
