xilinx: pm_service: Rename macros to use generic macro names 

ZynqMP pm_service ipi file uses platform specific macros names.
pm_service ipi functions can be used by other Xilinx platforms
also. Make rename macros to use generic names so that it can be
used by common file.

pm_service ipi functions will be moved to common file in next patch.
