[Libva] [PATCH] libva-intel-driver: Implement max width and height in QuerySurfaceAttributes

[Sean V Kelley]

From: Heng-ruey Hsu <henryhsu at chromium.org>

With this, we can get hardware supported resolution for video encode and
decode. This CL is used to prepare GetSupportedResolution in chrome.
