r600g: get s3tc working on cards with crappy 64/128 bit types.
Some cards don't appear to work correctly with the UNORM type, so switch to the integer type, however since gallium has no integer types yet from what I can see we need to do a hack to workaround it for the blitter. Signed-off-by: Dave Airlie <airlied@redhat.com>
