drm: kernel-doc: document drm_dp_set_subconnector_property() params

Changeset e5b92773287c ("drm: report dp downstream port type as a subconnector property")
added a new function to the kAPI, but didn't add any documentation
for the parameters for drm_dp_set_subconnector_property().

Fixes: e5b92773287c ("drm: report dp downstream port type as a subconnector property")
