panfrost: Identify Bifrost texture format swizzle
We don't force w=1 for Bifrost textures. We already compose this into
the swizzle as necessary, so we can just ignore this field I think. But
let's identify it so we don't forget what it is.
The blob uses it to force w=1 for <= 3-channel formats (0x10), as well
as a flag to swap r/b for BGRA (0x4). There are probably other flags
here but it doesn't.. really matter to us.
