drm/cec: add drm_dp_cec_attach() as the non-edid version of set edid
Connectors have source physical address available in display
info. There's no need to parse the EDID again for this. Add
drm_dp_cec_attach() to do this.
Seems like the set_edid/unset_edid naming is a bit specific now that
there's no need to pass the EDID at all, so aim for attach/detach going
forward.
v2: Fix the embarrashing build failures
