drm/i915: support page flipping on ValleyView
And restructure the IRQ handling a little. We can use pipestat for most things, and make sure we don't affect pipe events when enabling and disabling vblank interupts. We can leave vblank interrupts masked but enabled so we're not dependent on the first client to toggle the disable timer. We can also mask all render based interrupts, since the ring code will handle unmasking them for us. v2: roll in vblank masking, remove unneeded variable (Daniel) Signed-off-by: NJesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: NDaniel Vetter <daniel.vetter@ffwll.ch>
