NAK. Please pass this on the command line, or have VAAPI provide a way to query
this.

We have many devices using VAAPI and VAAPI doesn't support to query supported
resolution. Ivy Bridge+ supports 4K decode. So I think to use CPU detection only
for x86 CrOS is fine and it is used for a long time. We can keep it until VAAPI
supports resolution querying.
