This is becoming a common feature for Intel SoCs to expose the additional digital temperature sensors (DTSs) using side band interface (IOSF). This change remove common IOSF DTS handler function from the existing driver intel_soc_dts_thermal.c and creates a stand alone module, which can be selected from the SoC specific drivers. In this way there is less code duplication. Signed-off-by: Srinivas Pandruvada <srinivas.pandruvada@linux.intel.com>
