Since the pipe config is built up from scratch for modeset_pipes,
aren't we losing track of which PLL we were using previously?
We only unref the previous PLL for modeset_pipes in
ironlake_crtc_mode_set() by which time we've replace the pipe config
with the newly computed one.
For disable_pipes we en up in ironlake_crtc_off() which will do the
right thing since it still has the original pipe config to consult.
