Subject: Handle CRTC DPMS from output DPMS hooks
This fixes at least two issues:
The CRTC DPMS hook isn't called after a modeset, so the vertical blank
interrupt emulation code considered the CRTC disabled after a modeset. As
a side effect, page flipping was no longer used after a modeset.
This change also makes sure the vertical blank interrupt emulation code
runs before the hardware CRTC is disabled and after it's enabled from the
output DPMS hook. The wrong order could cause gnome-shell to hang after
a suspend/resume and/or DPMS off/on cycle.
