[PATCH v2 3/3] drm/tilcdc: panel: Add WARN() with a comment to tilcdc-panel probe

[Jyri Sarha]

Add WARN() to the beginnig of tilcdc-panel probe. The obsolete
tilcdc-panel driver should not be used anymore, since tilcdc is fully
capable of using generic drm panels like panel-simple and panel-common
binding.
