[PATCH] drm/tidss: Add prepare_fb to the plane helper funcs

[Jyri Sarha]

From: Gowtham Tammana <g-tammana at ti.com>

drm_gem_fb_prepare_fb() extracts fence and attaches to plane state.
The fence info is needed if implicit fencing is used. Add this as
prepare_fb function pointer to plane helper funcs.
