util/format: 8-bit interleaved YUV formats are UNORM

Browse source 
Without this, gallivm doesn't know what to do with the result data of a
texture fetch.  We have a bunch of gallivm code to handle these but, as
far as I can tell, none of it works properly without channel types.  The
YUYV texturing helpers all consume a 32-bit packed value, unpack it,
shuffle things as needed, and then re-pack into a 32-bit RGBA value,
trusting later code to unpack that as 8-bit UNORM.  For the raw formats,
this unpacking never happens.

What saves us is that I also don't think any of this code is ever used.
LLVMpipe supports the actual YUYV formats and we don't use the gallium
lowering pass which lowers to the raw formats.
