drivers/misc/qseecom.c:3724:28: error: cast to smaller integer type 'uint32_t' (aka 'unsigned int') from 'void *' [-Werror,-Wvoid-pointer-to-int-cast]
                        send_data_req.rsp_ptr = (uint32_t)req->resp_buf;
                                                ^~~~~~~~~~~~~~~~~~~~~~~

Fix `send_data_req.rsp_ptr = (uint32_t)req->resp_buf;` by casting
pointer value into uintptr_t, then compiler assignment will truncate to 32bit
to fit `uint32_t send_data_req.rsp_ptr` later.
