power: supply: ds2760_battery: merge ds2760 supply driver with its w1 slave companion
This patch removes the w1 slave driver that used to register the w1 family and instanciate a platform device at runtime. The code now lives in the supply driver instead to avoid that level of indirection. The old device name "ds2760-battery.0" is preserved, so userspace applications can access the same virtual device nodes as before. Note that because the w1 core does not currently have a framework for suspend/resume, the driver now registers a PM notifier callback.
