[PATCH 6/7] anv: add VK_EXT_display_control to anv driver [v2]

Fri Jun 15 02:52:55 UTC 2018
This extension provides fences and frame count information to direct
display contexts. It uses new kernel ioctls to provide 64-bits of
vblank sequence and nanosecond resolution.
v2: Adopt Jason Ekstrand's coding conventions
Declare variables at first use, eliminate extra whitespace between
types and names. Wrap lines to 80 columns.
Add extension to list in alphabetical order
