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.

w1: new w1_ds2406 driver

Some preliminary work at making use of this driver led me to implement
CRC-16 checks on read and write to deal with the occasional glitchiness of
the 1-Wire bus. The revised driver (attached) returns an I/O error if the
CRC check fails. When reading the chip's state, either you get a valid
indication or you get an I/O error. When changing its state, either the
change is successful or an I/O error is returned.

are represented as a own line in w1_slave file. Driver has been tested on
mips and x86.
