hwmon: (lm87) Add support for configuration through platform_data
The lm87 driver normally assumes that firmware configured the chip
correctly. Since this is not always the case, alllow platform code to
set the channel register value via platform_data. All other
configuration registers can be changed after driver initialisation.
