drivers: remoteproc: Add Xilinx r5 remoteproc driver 



This driver enables r5f dual core Real time Processing Unit subsystem
available on Xilinx Zynq Ultrascale MPSoC Platform. RPU subsystem
(cluster) can be configured in different modes e.g. split mode in which
two r5f cores work independent of each other and lock-step mode in which
both r5f cores execute same code clock-for-clock and notify if the
result is different.

The Xilinx r5 Remoteproc Driver boots the RPU cores via calls to the Xilinx
Platform Management Unit that handles the R5 configuration, memory access
and R5 lifecycle management. The interface to this manager is done in this
driver via zynqmp_pm_* function calls.
