The BUCK regulators 3, 4, and 5 also have a 10mV step mode,
adjust the tables and logic to reflect the data-sheet for
these regulators.

I just got word that there was a typo in the datasheet, 0x0 really does
map to 0v out, the above change chunk can be dropped. It looks this
patch also just got pulled, should I submit a correction patch or can
this be fixed up locally?
Thanks,
Andrew

A followup would be easier if only to make sure I don't make any
mistakes.
