Provide basic driver to control Arm R5  co-processor found on
Xilinx ZynqMP UltraScale+ and Versal MPSoC's.

Currently it is able to start, stop and load elf on to the
processor.

The driver was tested on Xilinx ZynqMP and Versal.

Changes since v1:
- remove domain struct as per review from Mathieu
Changes since v2:
- add xilinx-related platform mgmt fn's instead of wrapping around
  function pointer in xilinx eemi ops struct
- update zynqmp_r5 yaml parsing to not raise warnings for extra
  information in children of R5 node. The warning "node has a unit
  name, but no reg or ranges property" will still be raised though 
  as this particular node is needed to describe the
  '#address-cells' and '#size-cells' information.
changes since v3:
- add default values for enums
- fix formatting as per checkpatch.pl --strict. Note that 1 warning and 1 check
  are still raised as each is due to fixing the warning results in that
particular line going over 80 characters.
- remove warning '/example-0/rpu@ff9a0000/r5@0: 
  node has a unit name, but no reg or ranges property'
  by adding reg to r5 node.
