thermal/drivers/qcom: Add support for PMIC5 Gen2 ADCTM

Add support for PMIC5 Gen2 ADC_TM, used on PMIC7 chips. It is a
close counterpart of PMIC7 ADC and has the same functionality as
PMIC5 ADC_TM, for threshold monitoring and interrupt generation.
It is present on PMK8350 alone, like PMIC7 ADC and can be used
to monitor up to 8 ADC channels, from any of the PMIC7 PMICs
having ADC on a target, through PBS(Programmable Boot Sequence).
