Since the cv-port extension was literally just this one URI, the port
type doesn't really introduce anything new (same format as
lv2:AudioPort, used like an lv2:ControlPort), and abuse of audio ports
for this has been around since the early LADSPA days, I just moved this
to the core spec.  So, lv2:CVPort is the type now.
