The driver ignores the flag for compressed formats. It doesn't ignore
the flag for depth/stencil formats, but it does support binding a
linear depth/stencil buffer as a color buffer.

That said, I think PIPE_BIND_LINEAR should not be an allowed parameter
of is_format_supported (unless we have a very good reason to allow it).
