xilinx: Move IPI functions to common file ...

pm_service ipi functions can be used by other xilinx
platforms. So move it to common directory. Also change
node_id member type in pm_proc structure so it can be
used for versal where device IDs are used instead of
node IDs.

To accommodate this change header files are re-organized.
