mailbox: mediatek: Add Mediatek CMDQ driver

2018-08-03T14:22:14Z

This patch is first version of Mediatek Command Queue(CMDQ) driver. The CMDQ is used to help write registers with critical time limitation, such as updating display configuration during the vblank. It controls Global Command Engine (GCE) hardware to achieve this requirement. Currently, CMDQ only supports display related hardwares, but we expect it can be extended to other hardwares for future requirements.
