And put the pfit stuff into substructs while we're at it.

So this patch made it to drm-intel-next-queued and the line above
causes "unclaimed register" errors. This happens even if we don't
disable the power well, and we were 100% clear of these error messages
on that case, so I guess I can call this a "regression". Can you
please provide a fix?

Well, that hunk switches from checking dev_priv->pch_pf_size (which is
now in crtc->config, so we'd need to check the right
pipe/cpu_transcoder first) to the register value, which is just plain
bogus.

While at it we could fix the XXX in haswell_crtc_disable, which is now
possible with the pch pfit tracking.
