For correct operation Lager DIP switches SW5 and SW6 shall be

If the DIP switch is configured incorrectly then the user can
simply adjust the hardware and either reboot or use the bind interface
to try to probe again:

This makes it more like other devices, no need to be special.

Also, these ifdefs by themselves do not hurt much, but combined
with USB Host device ifdefs that were proposed earlier we could
basically end up with a kernel that drives VBUS incorrectly
