Yeah that makes sense where we need to pass in the right pipe_config. But
in the _enable functions just using to_intel_crtc_state(crtc->state) is
ok, and just doing that would cut down on the overall diff. Same idea as
not passing pipe_config around explicitly for other functions only called
from _enable hooks (and other places where crtc->state is the right
state).
I'm ok with open-coding the dpll lookup in compute/disable/get_config functions.

i9xx_update_primary_plane doesn't have any shared dpll code, which means
this s/crtc->config/pipe_config replacement should probably be in a
different patch.
