power_supply: Add support for writeable properties
This patch adds support for writeable power supply properties and
exposes them as writeable to sysfs.
A power supply implementation must implement two new function calls in
order to use that feature:
int set_property(struct power_supply *psy,
enum power_supply_property psp,
const union power_supply_propval *val);
int property_is_writeable(struct power_supply *psy,
enum power_supply_property psp);
