Follow-up of kernel patch: https://lists.freedesktop.org/archives/dri-devel/2015-July/086041.html

Generate it using `make headers_install`

ChromeOS will use new format to optimize video decoding.

Hi Stéphane and Daniele,

Could you give me lgtm?
Daniel wants someone from client side to ack this change in order to land
it.
