thermal: make THERMAL_HWMON implementation fully internal
THERMAL_HWMON is implemented inside the thermal_sys driver and has no effect on drivers implementing thermal zones, so they shouldn't see anything related to it in <linux/thermal.h>. Making the THERMAL_HWMON implementation fully internal has two advantages beyond the cleaner design: * This avoids rebuilding all thermal drivers if the THERMAL_HWMON implementation changes, or if CONFIG_THERMAL_HWMON gets enabled or disabled. * This avoids breaking the thermal kABI in these cases too, which should make distributions happy. The only drawback I can see is slightly higher memory fragmentation, as the number of kzalloc() calls will increase by one per thermal zone. But I doubt it will be a problem in practice, as I've never seen a system with more than two thermal zones.
