Because that's what we're essentially calling. This is the first step
in untangling the crtc_helper induced dpms handling mess we have - at
the crtc level we only have 2 states and the magic is just in
selecting which one (and atm there isn't even much magic, but on
recent platforms where not even the crt output has more than 2 states
we could do better).
