Subject[PATCH 2/5] power_supply: fix up olpc_battery's eeprom read function

The eeprom read function was placing values into the wrong place in
'buf'; we were starting from buf[off], rather than buf[0].

Also, the for loop that we were using was much uglier than it needed to
be. This cleans it up a bit.
