[PATCH v2 03/10] drm: mali-dp: Use __drm_atomic_helper_plane_reset instead of copying the logic

[Alexandru Gheorghe]

A new helper function(__drm_atomic_helper_plane_reset) has been added
for linking a plane with its state and resetting the core
properties(alpha, rotation, etc.) to their default values.
Use that instead of duplicating the logic.
