Since these driver structures differ only in name there seems to be no
need to define more than one for the bucks and one for the LDOs - the
code in the driver doesn't actually seem to need it.  The .id field of
the driver structure can be set to give the device numbers.

This MODULE_ALIAS won't actually work - the name doesn't match up with
the names of the drivers or the devices.
