thermal: Create CONFIG_THERMAL_HWMON=n
A bug in libsensors <= 2.10.6 is exposed
when this new hwmon I/F is enabled.
Create CONFIG_THERMAL_HWMON=n
until some time after libsensors 2.10.7 ships
so those users can run the latest kernel.
libsensors 3.x is already fixed -- those users
can use CONFIG_THERMAL_HWMON=y now.
