[PATCH v3 0/2] Add mode_valid hook for sii902x bridge

[Jayesh Choudhary]

Currently, there are no check to validate the modes in the bridge.
Add pixel clock check to validate the modes that the bridge can support.

Also add the mode_valid hook in 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.

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

Changelog v2->v3:
- Remove newline that was introduced in [1/2] and later deleted in [2/2]
  in v2
