panfrost: Complete format_to_bifrost_blend
Instead of matching on the PIPE format directly, match on the internal
format of the tile buffer and pick the pixel format that corresponds to
the internal tile buffer format (which differs from the format written
back to memory in the general case).
We add a number of missing formats to accomodate this, including the
AU/PU variants of each tilebuffer pixel format, where the AU formats use
the extra bits to store extra precision for dithering but the PU formats
simply pad the extra bits with zeroes. For the moment we use AU
everywhere. I'm not sure if there's a cost associated.
