i965/gen8: Allow rendering to B8G8R8X8
Since Gen8 this is allowed as a rendering target so we don't need to override it to B8G8R8A8. This is helpful on Gen9+ where using this override causes fast clears not to work. Reviewed-by: Anuj Phogat <[email protected]> Reviewed-by: Ben Widawsky <[email protected]>
