[openfirmware] [commit] r3393 - in cpu/arm/olpc: . cl4

Log:
OLPC ARM - assign "0 0 reg" properties to several devices

when linux names devices, devices without a reg property will
get a globally assigned incrementing suffix, which may change
depending on which devices are configured.  if present, linux
will use the reg property to create a stable name for a device.
using "0 0 reg" will result in a linux name like "0.ols"
