[Mesa-dev] [PATCH] nvc0: add support for BGRA8 images

This is useful for pbo downloads, which are now accelerated with images.
BGRA8 is a moderately common format to do that in.

This needs testing on SM20 and SM30. I've tested it on SM35 and
bin/pbo-readpixels-small -auto
worked fine. (Didn't until I properly fixed the various items.)
