I don't like this.

Ideally, there should be feedback from the display server so that he
state tracker(s) can set the PIPE_BIND_SCANOUT flag only when it's
really necessary.

In the meantime, if we want to go for a hack like this, it should be in
the place(s) setting the flag instead of the driver ignoring it.

If there's any code setting PIPE_BIND_SCANOUT for such surfaces, it's
buggy and should be fixed.
