Daniel Stone c9fbb7f7b5 drm/rockchip: Use CRTC vblank event interface 
Passing -1 as the pipe for vblank events now triggers a WARN_ON, but had
previously made multi-screen unusable anyway. Pass the correct pipe to
the event-send function, and use the new API to make this a bit easier
for us.

Fixes WARN present since cc1ef118fc for every pageflip event sent:
