Alyssa Rosenzweig bfba7533c7 panfrost: Add Valhall Plane Descriptor XML 
This looks superficially like the Bifrost "Surface" descriptor, but it
additionally specifies the in-memory representation of blocks (clumps). If I
understand correctly, decompression is controlled by the plane descriptor,
rather than the texture descriptor level. This is a bit more flexible than
Bifrost.

Once the new fields here are wired up to Mesa, my
dEQP-GLES2.functional.texture.* failures should go away... I hope!
