drm/i915: s/pipe_config/crtc_state/ in the state checker

Switch over to the modern variable naming in the state checker.
Ie. rename the pipe_config stuff to crtc_state.

Also make it clear which is the "software state" (ie. what the
current state should be) vs. "hardware state" (ie. what the
currnet state really is).
