[PATCH v5 0/3] SII902X HDMI Bridge fixups

[Jayesh Choudhary]

- 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.
