This patch removing set_mode_hook function from board data and replacing
it with new string variable of notifier power supply device. After this
change it is possible to add DT support because driver does not need
specific board function anymore. Only static data and name of power supply
device is required.

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.
