drm/imx: Use __drm_atomic_helper_plane_reset instead of copying the logic

Browse Source 
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.
