Use the core destroy_state helpers to destroy core state to ensure we don't
leak if/when more fields get added later.

Now that mtk_drm_plane just contains its base struct drm_plane, we can
just remove it and use struct drm_plane everywhere.

It is not actually useful to a mtk plane to know its zpos/index, so just
remove this field.

This let's completely remove struct mtk_drm_plane in a follow up patch.

It's unused, and really this helper should only look at the state
structure and nothing else.

v2: Rebase on top of rockchip changes

v3: Drop unrelated hunk, spotted by Laurent.

v4: Rebase onto mtk driver merge.

This patch adds an initial DRM driver for the Mediatek MT8173 DISP
subsystem. It currently supports two fixed output streams from the
OVL0/OVL1 sources to the DSI0/DPI0 sinks, respectively.
