drm/bridge_connector: rely on drm_kms_helper_poll_* for HPD enablement

Browse source

Use drm_connector's helpers enable_hpd and disable_hpd to enable and
disable HPD automatically by the means of drm_kms_helper_poll_*
functions. As the drm_bridge_connector_enable_hpd() and
drm_bridge_connector_disable_hpd() functions are now unused, replace
them with stubs to ease driver migration.

Enabling the HPD from drm_bridge_connector_init() can happen too early,
before the driver is prepared to handle HPD events. As the
drm_bridge_connector_enable_hpd() is empty anyway, drop this call
anyway.
