drivers: w1: Extend 1W master driver DS2482 with module option to support PPM/SPU/1WS features

Extend the one wire DS2482 master driver with a module option that allows support
for PPM/SPU/1WS interface modes to be requested. This allows support of chips
that require one or more of these features such as the DS28E05.
