drm/bridge: chrontel-ch7033: Switch to atomic bridge callbacks

Browse Source 
The chrontel-ch7033 bridge uses the legacy non-atomic enable and disable
bridge callbacks.

In order to remove the legacy bridge callback support from the DRM
bridge core, switch to their atomic counterparts and add the bridge
atomic state handlers.
