[Intel-gfx] [PATCH 2/2] drm/i915: Use new kms-native vblank functions

Only the low-level irq handling functions still use integer crtc
indices with this. But fixing that will require a lot more sugery
and some good ideas for backwards compat with old ums userspace.
Both in drivers and in the drm core.
