At the moment this driver fails to load if no encoders/connectors were
found. In case other drivers that register encoders/connectors
(tilcdc_panel) are defered it would be better to check for
encoders/connectors later again. This patch replaces the returncode
-ENXIO with -EPROBE_DEFER to get a working setup even if tilcdc_panel
probes after tilcdc.
