Rodrigo Siqueira 3a0709928b drm/vkms: Add vblank events simulated by hrtimers 
This commit adds regular vblank events simulated through hrtimers, which
is a feature required by VKMS to mimic real hardware. Additionally, all
the vblank event send after pageflip is kept in the atomic_flush
function.

Changes since V1:
 - Compute the vblank timer interval per interruption
 Ville Syrjälä and Daniel Vetter:
 - Removes hardcoded vblank interval to get it from user space

Changes since V2:
 Chris Wilson
 - Removes unnecessary algorithm to compute the next period
 Daniel Vetter:
 - Uses drm_calc_timestamping_constants to get the vblank interval
   instead of calculating it manually
 - Adds disable_vblank helper that turns of crtc
 - Simplifies implementation by using drm_crtc_arm_vblank_event
 - Replaces the code in atomic_begin to atomic_flush
 - Removes unnecessary field in vkms_output

Changes since V3:
 Daniel Vetter:
 - Squash "drm/vkms: Add atomic helpers functions" into the commit that
   handling vblank events simulated by hrtimers
