drm/i915: Use pipe state to tell when pipe is off
Instead of waiting for the display line value to settle, we can simply
wait for the pipe configuration register 'state' bit to turn off.
Contrarywise, disabling the plane will not cause the display line
value to stop changing, so instead we wait for the vblank interrupt
bit to get set. And, we only do this when we're not about to wait for
the pipe to turn off.
