firmware: xilinx: Update firmware call interface to support additional args
System-level platform management layer (do_fw_call()) has support for
maximum of 5 arguments as of now (1 EEMI API ID + 4 command arguments).
In order to support new EEMI PM_IOCTL IDs (Secure Read/Write), this
support must be extended to support one additional argument, which
results in a configuration of - 1 EEMI API ID + 5 command arguments.
Update zynqmp_pm_invoke_fn() and do_fw_call() with this new definition
containing variable arguments. As a result, update all the references
to pm invoke function with the updated definition.
