drm/vc4: hdmi: Simplify the connector state retrieval

Browse Source 
When we have the entire DRM state, retrieving the connector state only
requires the drm_connector pointer. Fortunately for us, we have
allocated it as a part of the vc4_hdmi structure, so we can retrieve get
a pointer by simply accessing our field in that structure.
