drm/sun4i: tv: Get tcon and backend pointers from associated crtc
The drm_encoder structure provides us with a pointer to the crtc currently tied to the encoder. Subsequently we can extract the tcon and backend pointers from our crtc structure, instead of getting it directly from the sun4i_drv structure.
