BSD does not statically assign things by default like this, which is what
makes this wrong.  We will never do this by default, as there's far too many
possible combinations of controllers to assign statically which one gets
scsibus0, not to mention sd0.

Note that I'm not arguing against a locator-based scheme, just indicating
why engineering it into our current device model will not work.
