Thomas Zimmermann d54dbb5963 drm/vblank: Add CRTC helpers for simple use cases
Implement atomic_flush, atomic_enable and atomic_disable of struct
drm_crtc_helper_funcs for vblank handling. Driver with no further
requirements can use these functions instead of adding their own.
Also simplifies the use of vblank timers.

The code has been adopted from vkms, which added the funtionality
in commit 3a0709928b ("drm/vkms: Add vblank events simulated by
hrtimers").

v3:
- mention vkms (Javier)
v2:
- fix docs
