Subject: [PATCH 11/14] POWER: bq27x00: Give more specific reports on battery status

The current code only reports whether the battery is charging or discharging.
But the battery also reports whether it is fully charged, furthermore by look at
if the battery is supplied we can tell whether it is discharging or not
charging.
