Bug description:
  OS version: Ubuntu 18.04 beta rc
  Hardware: Intel core i5 7400 (Kaby lake processor)
  with Intel HD graphics 630 supporting VP9 10-bit and 8-bit video decoding.

  In version 1.8.x of the driver the VP9 decoding is broken, the
  corresponding upstream patch got into 2.0.0. But since VP9 profiles
  are missing in version 2.0.0 driver in Ubuntu 18.04, hardware
  acceleration is absent, so high cpu and power usage. The buggy driver
  1.8.x is used in the vlc snap too and snap developers doubt the driver
  version in snap will be upgraded.

  * VP9 decoding broken in 17.10
  * VP9 decoding broken in snap packages

  Either driver version has to be updated to 2.1.0 or at-least cherry
  pick a one line patch to current Ubuntu core snap, a link for which I
  will mention below.

  Upstream driver patch: https://github.com/intel/intel-vaapi-
  driver/commit/9d66570032fb02b1e79a883af7697b035d700a8e

  Upstream bug report: https://github.com/intel/intel-vaapi-
  driver/issues/297

  In any way kindly support VP9 hardware decoding via supported Intel
  hardwares in in 17.10(by backporting driver v2.1.0/cherry picking
  upsteam patch) or atleast via updated snap core/apps.
