Subject: [PATCH 0/2] Add vcp driver

Add support MediaTek's Video Companion Processor(VCP) host driver to
control the MediaTek VCP Risc-V coprocessor.
The VCP host driver using rproc mechanism to load vcm firmware
from filesystem, and using SMC services to request ATF to setting
vcp boot sequence, and Host communicated with VCP FW depends on VCP
IPC interfaces
