[ Upstream commit 5abc174016052caff1bcf4cedb159bd388411e98 ]
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.
