arm64: dts: qcom: sc8280xp-x13s: Add PM8280_{1/2} ADC_TM5 channels

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