[PATCH 1/2] drm/mediatek: add plane check in async_check function

[Bibby Hsieh]

MTK do rotation checking and transferring in layer check function,
but we do not check that in atomic_check,
so add back in atomic_check function.

Fixes: 920fffcc8912 ("drm/mediatek: update cursors by using async atomic update")
