Chris Wilson 5bb61643f6 drm/i915: Flush the pending flips on the CRTC before modification
This was meant to be the purpose of the
intel_crtc_wait_for_pending_flips() function which is called whilst
preparing the CRTC for a modeset or before disabling. However, as Ville
Syrjala pointed out, we set the pending flip notification on the old
framebuffer that is no longer attached to the CRTC by the time we come
to flush the pending operations. Instead, we can simply wait on the
pending unpin work to be finished on this CRTC, knowning that the
hardware has therefore finished modifying the registers, before proceeding
with our direct access.

Fixes i-g-t/flip_test on non-pch platforms. pch platforms simply
schedule the flip immediately when the pipe is disabled, leading
to other funny issues.
