Subject: [PATCH 6/7] drm/mediatek: support CMDQ interface in ddp component
The CMDQ (Command Queue) in MT8183 is used to help
update all relevant display controller registers
with critical time limation.
This patch add cmdq interface in ddp_comp interface,
let all ddp_comp interface can support cpu/cmdq function
at the same time.
