Just an aside, in case you get around to decoding modifiers: We should
probably switch to printing the fourcc code and decode that while at it.
And perhaps print the stride too, since with the new tiling there will be
no underlying fence any more to guess the stride.

Perhaps we need a describe_fb helper to keep this manageble, too.
