Revert "drm/mediatek: Clear pending flag when cmdq packet is done"

This reverts commit c20745db808a1e00a78d819d425e1b6402ea989d.

Commit d4377f43afa9
("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.
