drm/gem: Export implementation of shadow-plane helpers

Browse source

Export the implementation of duplicate, destroy and reset helpers for
shadow-buffered plane state. Useful for drivers that subclass struct
drm_shadow_plane_state.

The exported functions are wrappers around plane-state implementation,
but using them is the correct thing to do for drivers.
