drm: make mode_valid callback optional
Many drm connectors do not need mode validation.
The patch makes this callback optional and removes dumb implementations.
v2: Rebase:
- imx move to a shared (but still dummy) ->mode_valid implementation.
- probe helpers have been extracted to drm_probe_helper.c
