  Add ADC_TM5 channels of PM8280_{1/2} for monitoring the temperature from
external thermistors connected to AMUX pins. The temperture measurements
are collected from the PMK8280's VADC channels that expose the
measurements from secondary PMICs PM8280_{1/2}.

If you decide to change the order in the prev patches, it applies here too.
