I recently ran some igts on my i915gm and i945gm and noticed
that the CRC interrupt suffers from the same C-state issue
that vblank interrupts had. I guess that shuld come as a
no surprise to me. So we need to extend the clock gating
disable trick to CRC interrupts as well.
I also got fed up with the state of the vblank enable/disable
functions, and proceeded to do some cleanup.
