Wire up CRTCs', planes' and connectors' ->reset, ->duplicate and ->destroy state
hooks to use the default implementations from the atomic helper library.
The helpers track each DRM object state.

v3->v4:
* None.
v2->v3:
* For dw-hdmi bridge driver, simply add the hooks to the legacy connector
function structure instead of using the atomic version directly, because
we are not yet ready to use the atomic version's ->dpms hook.
v1->v2:
* Remove the 'atomic' from the name of the structure
dw_hdmi_atomic_connector_funcs to address Philipp's comment.
