drivers: remoteproc: xlnx: Add Versal and Versal-NET support

Browse Source 
AMD-Xilinx Versal platform is successor of ZynqMP platform.
Real-time Processing Unit R5 cluster IP on Versal is same as
of ZynqMP Platform. Power-domains ids for Versal platform is
different than ZynqMP.

AMD-Xilinx Versal-NET platform is successor of Versal platform.
Versal-NET Real-Time Processing Unit has two clusters and each
cluster contains dual core ARM Cortex-R52 processors. Each R52
core is assigned 128KB of TCM memory.
