drm/plane-helper: Provide DRM_PLANE_NON_ATOMIC_FUNCS initializer macro

Browse Source 
Provide DRM_PLANE_NON_ATOMIC_FUNCS, which initializes plane functions
of non-atomic drivers to default values. The macro is not supposed to
be used in new code, but helps with documenting and finding existing
users.
