bq27x00_battery: Call power_supply_changed only when capacity changed
In current driver, power_supply_changed() is called whenever any of the battery attribute changed. This causes kernel to increases the '/sys/power/wakeup_count' and make suspend not working correctly. This patch change this behavior to call power_supply_changed() only when the battery capacity changed.
