As per the datasheets, maximum battery regulation voltage is 4440mV.
The formula is (voltage - offset) / step, so the maximum value is:
(4440 - 3500) / 20 = 47

* Renamed mode BQ2415X_MODE_NONE to BQ2415X_MODE_OFF because this mode
turning chaging completly off
* Added new mode BQ2415X_MODE_NONE which enable charging with maximal
current limit 100mA (this is minimal safe value for bq2415x chips)

I hate doing these style fixups myself, but I also hate inconsitent code.
Normally I just ask to resubmit the patch with the issues fixed, but N900
is special: I have a selfish interest in it. :)

The bq2415x charger driver is needed for example on Nokia N900 for
charging battery. Driver is part of open source project to replace
proprietary battery management.
