Thermal: move the KELVIN_TO_MILLICELSIUS macro to thermal.h
This macro can be used by other component so move it to a common header, but in a slightly different way: define two macros, one macro with an offset and the other doesn't. Signed-off-by: Aaron Lu <aaron.lu@intel.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
