This mapping is used in the pmic thermal driver to notify the thermal zone with the pmic adc channel alert interrupts. This patch also adds three new data structures to include/linux/mfd/intel_soc_pmic.h: struct trip_config_map{}, struct thermal_irq_map {} and struct pmic_thermal_data {} which are required by changes we did on intel_soc_pmic_bxtwc.c.
