Jayesh Choudhary 6dbff34016 drm/bridge: cadence: cdns-mhdp8546-core: Add mode_valid hook to drm_bridge_funcs
Add cdns_mhdp_bridge_mode_valid() to check if specific mode is valid for
this bridge or not. In the legacy usecase with
!DRM_BRIDGE_ATTACH_NO_CONNECTOR we were using the hook from
drm_connector_helper_funcs but with DRM_BRIDGE_ATTACH_NO_CONNECTOR
we need to have mode_valid() in drm_bridge_funcs.

Without this patch, when using DRM_BRIDGE_ATTACH_NO_CONNECTOR
flag, the cdns_mhdp_bandwidth_ok() function would not be called
during  mode validation, potentially allowing modes that exceed
the bridge's bandwidth capabilities to be incorrectly marked as
valid.
