firmware: xilinx: Dont send linux address to get fpga config get status
Fpga get config status just returns status through ret_payload and there
is no need to allocate local buf and send its address through SMC args.
Moreover, the address that is being passed till now is linux virtual
address and is incorrect.
Corresponding modification has been done in the firmware to avoid using the
address sent by linux.
