Subject: [PATCH v4 0/2] Add mode_valid and atomic_check hooks for sii902x bridge

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.

Changelog v3->v4:
- Remove mode_valid hook from connector_helper_funcs as it is not needed.

v3 patch:
<https://lore.kernel.org/all/20240524093509.127189-1-j-choudhary@ti.com/>

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

v2 patch:
<https://lore.kernel.org/all/20240524073305.107293-1-j-choudhary@ti.com/>

Changelog v1->v2:
- Add KHZ suffix in the macros to be more clear
- Add the hook for drm_bridge_funcs as well
- Add check in atomic_check dunction call (in a separate patch)

v1 patch:
<https://lore.kernel.org/all/20240408081435.216927-1-j-choudhary@ti.com/>

  drm/bridge: sii902x: Fix mode_valid hook
