[PATCH 13/19] Thermal: move the KELVIN_TO_MILLICELSIUS macro to thermal.h
From: Zhang Rui <rui.zhang@intel.com>

From: Aaron Lu <redacted> 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.
