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.
These patches also can fixup cursor moving is not smooth when heavy load in webgl.
