w1: ds2760_battery: add support for sleep mode feature
This adds support for ds2760's sleep mode feature. With this feature enabled, the chip enters a deep sleep mode and disconnects from the battery when the w1 line is held down for more than 2 seconds. This new behaviour can be switched on and off using a new module parameter.
