These refinements include using standard mailbox callback interface, timeout detection, and a fixed cmdq_handle.
Change in v3: 1. Revert "drm/mediatek: clear pending flag when cmdq packet is done" and add it after the CMDQ refinement pathes. 2. Change the remove of struct cmdq_client to remove the pointer of struct cmdq_client. 3. Fix pkt buf alloc once but free many times.
Changes in v2: 1. Define mtk_drm_cmdq_pkt_create() and mtk_drm_cmdq_pkt_destroy() when CONFIG_MTK_CMDQ is reachable.
