[V7,0/5] add display support for MediaTek SoC MT8186

v7:
1. Rebase to chunkuang.hu/linux.git mediatek-drm-fixes

v6:
1. Remove mmsys patches which are accepted.
2. Fix error of dt-binding.

v5:
1. Add binding patch of aal for MT8183.
2. Revise enum to const.
3. Change to use enum for mutex.
4. Remove patches which are accepted by maintainers. (mmsys and mutex)

v4:
1. Remove binding of dsi and dpi.
2. Revise aal binding.
3. Fix indention in [4/5].

v3:
1. Modify display binding based on mtk display binding patch. ([1])
2. Remove patch: drm/mediatek: separate postmask component from mtk_disp_drv.c
3. Remove compatible of 8186 ovl because we can re-use compatible of 8192 for 8186.
4. Fix issue of space before tab on mutex patch.

v2:
1. Add binding documentation for mmsys, mutex and mtk_display.
2. Remove duplicated definition of postmask registers on mtk_drm_drv.
3. Add disp_ovl support for MT8186.
4. Add detailed commit messages.
