olpc_battery: Add support for CURRENT_NOW and VOLTAGE_NOW

{CURRENT,VOLTAGE}_AVG are actually {CURRENT,VOLTAGE}_NOW (the EC code
directly passes through the value from the gas gauge instead of the
internally used average). We retain {CURRENT,VOLTAGE}_AVG as an alias
for compatibility reasons, it will be removed later.
