Giulio Benetti a8939766c7 drm/sun4i: tcon: prevent tcon->panel dereference if NULL ...

If tcon->panel pointer is NULL, trying to dereference from it
(i.e. tcon->panel->connector) will cause a null pointer dereference.

Add tcon->panel null pointer check before calling
sun4i_tcon0_mode_set_dithering().
