drm/display: bridge_connector: provide atomic_check for HDMI bridges 



The bridges using HDMI connector framework have a call to
drm_atomic_helper_connector_hdmi_check() in their atomic_check()
callback. In order to reduce boilerplate and make simplify bridge's
code, use drm_atomic_helper_connector_hdmi_check() to implement
drm_connector.atomic_check() for HDMI bridges.
