Subject: [PATCH v2] power: supply: bq27xxx_battery: Notify also about status changes

User-space might be interested in receiving uevents when the charging
starts/stops or if conditions of battery changes (e.g.
over-temperature).  Notify about changes in battery also when the flags
change, not only SoC.

Signed-off-by: Krzysztof Kozlowski <krzk@...nel.org>
