Naman Trivedi 4146a31dce drivers: firmware: update xilinx_pm_request to support max payload
Currently xilinx_pm_request API supports four u32 payloads. However the
legacy SMC format supports five u32 request payloads and extended SMC
format supports six u32 request payloads. Add support for the same in
xilinx_pm_request API. Also add two dummy arguments to all the callers
of xilinx_pm_request.

The TF-A always fills seven u32 return payload so add support
for the same in xilinx_pm_request API.
