HID: logitech-hidpp: battery: provide CAPACITY property for newer devices
For devices that only support the BATTERY_VOLTAGE (0x1001) feature, UPower requires the additional information provided by this patch, to set them up. Signed-off-by: Hamza Mahfooz <someguy@effective-light.com> Reviewed-by: Filipe Laíns <lains@riseup.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
