[PATCH v3 6/6] thermal/drivers/intel_menlow: Make additionnal sysfs information optional

[Daniel Lezcano]

The Menlon thermal driver creates specific files in the thermal zone
sysfs class. It is specific to Menlon and these entries look debug
code. It is probable these are not needed.

Let's make the code optional and disable it by default.
