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

Other comments about node names stay as well, but it depends on the
previous discussion.
