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. Signed-off-by: Sascha Silbe <sascha-pgp@silbe.org> [ pgf@laptop.org: added VOLTAGE_NOW, aliased to VOLTAGE_AVG ] Signed-off-by: Paul Fox <pgf@laptop.org> Signed-off-by: Anton Vorontsov <cbouatmailru@gmail.com>
