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.
