- Move the mode_valid hook to drm_bridge_funcs structure to take care
  of the case when the encoder attaches the bridge chain with the
  DRM_BRIDGE_ATTACH_NO_CONNECTOR flag in which case, the connector is
  not initialized in the bridge's attach call and mode_valid is not
  called.

- Also add this check to the atomic_check call as suggested by Maxime in
  v1 patch.

- Move from deprecated enable()/disable() hooks to atomic hooks as
  suggested in v4 by Sam

Testing has been done on AM62X platform which have SII902X HDMI bridge.
From the logs we can see the propagated modes and flip test for 1080p
resolution.
