Subject: [PATCH v2 4/4] power: ds2760_battery: add device tree glue

The w1 slave device used by this driver now has a of_node in case it
was matched against a devicetree sub-node of the bus master. This can
now be passed down to the power supply core which will parse more
properties from the node, such as 'power-supplies'.
