mtk mutex is a driver used by DRM and MDP [1], so this series move
mtk mutex driver from DRM folder to soc folder, so it could be used
by DRM and MDP.
This series based on linux-next next-20201218 [2]

CK Hu (5):
drm/mediatek: Remove redundant file including
drm/mediatek: Rename file mtk_drm_ddp to mtk_mutex
drm/mediatek: Change disp/ddp term to mutex in mtk mutex driver
drm/mediatek: Automatically search unclaimed mtk mutex in
mtk_mutex_get()
soc / drm: mediatek: Move mtk mutex driver to soc folder
