Revert "drm/mediatek: Clear pending flag when cmdq packet is done"
This reverts commit 9efb16c2fdd647d3888fd8dae84509f485cd554e.
Commit c1ec54b7b5af
("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 and all the patches depend on that patch.
