I think there are two different things here: one is the driver
internally fakes BGRX with BGRA, and obviously it's the pipe driver that
needs to fix up alpha channel blending to simulate it's one.
The other is the state tracker is faking BGRX with BGRA, and in that
case, it's the state tracker
I can't say I like this. Ever since Radeon - Northern Islands, our
hardware can do this DST_ALPHA->ONE adjustment automatically, so the
new state dependency on _NEW_BUFFERS is unnecessary for us here.

So independent blend won't get enabled even though the backend
