As the kzm9d only has one smsc911x device it
may be registered as a platform device with id -1.

This allows the kzm9d board to access the smsc911x device
when CONFIG_REGULATOR (and CONFIG_REGULATOR_FIXED_VOLTAGE)
are set. The motivation for which is twofold: using regulators
seems to be generally a good thing; it will move the kzm9d defconfig
one step closer to being able to be consolidated with other
shmobile defconfigs.

An alternate but so far untested approach would be to
update the definition of dummy_supplies in board-kzm9d.c
to use "smsc911x.0" instead of "smsc911x".
