thermal: qcom: add support for adc-tm5 PMIC thermal monitor

Browse Source 
Add support for Thermal Monitoring part of PMIC5. This part is closely
coupled with ADC, using it's channels directly. ADC-TM support
generating interrupts on ADC value crossing low or high voltage bounds,
which is used to support thermal trip points.
