[Mesa-dev] [PATCH] radv: Disable multilayer & multilevel DCC.

[Bas Nieuwenhuizen]

The current DCC init routine doesn't account for initializing a
single layer or level. Multilayer seems hard for small textures on
pre-GFX9 as tre metadata for the layers can be interleaved. For
GFX9 multilevel textures are a problem for similar reasons.

So just disable this for now, until we handle the texture modes
correctly.
