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.
