drm/sti: hda: Switch to atomic bridge callbacks

Browse Source 
The hda bridge uses the legacy non-atomic pre_enable, enable, disable
and post_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.
