Revert "drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb"

Browse source 
This reverts commit c1ec54b7b5.

Commit c1ec54b7b5
("drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb")
would cause numerous mtk cmdq mailbox driver warning:

WARNING: CPU: 0 PID: 0 at drivers/mailbox/mtk-cmdq-mailbox.c:198
cmdq_task_exec_done+0xb8/0xe0

So revert that patch.
