Subject: [PATCH v22 0/5] Provide basic driver to control Arm R5 co-processor found on Xilinx ZynqMP

Update Xilinx R5 Remoteproc Driver as follows:
- update documented param list for zynqmp_r5_probe
- remove use-after-free lines in zynqmp_r5_probe,
  zynqmp_r5_remoteproc_probe, and zynqmp_r5_remoteproc_remove
- update path for error handling in zynqmp_r5_probe and
  zynqmp_r5_remoteproc_probe
- update zynqmp_r5_rproc_kick to only use mailbox-related
  properties if the rproc pointer's corresponding of_node
  has mbox properties present, otherwise kick should and will
  do nothing
