Introduce new enhancements in the remoteproc xlnx driver. Handle mailbox
optional properties gracefully. Handle buffer-less IPI without crash i.e.
no message is expected from the mailbox callback. Also gracefully free
mailbox channels during shutdown callback.
These small enhancements make driver more robust.

  remoteproc: xlnx: Only access buffer information if IPI is buffered

Tanmay Shah (2):
  remoteproc: xlnx: avoid mailbox setup
  remoteproc: zynqmp: release mailbox channels on shutdown
