Subject: [PATCH v10 1/4] soc: mediatek: mmsys: add support for MDP

For the purpose of module independence, related settings should be moved
from MDP to the corresponding driver.
This patch adds more 8183 MDP settings and interface. and MDP
related settings must be set via CMDQ to avoid frame unsynchronized.
