Subject: [PATCH v3 09/12] arm64: dts: qcom: sc8280xp-x13s: Add PM8280_{1/2} VADC channels

Add VADC channels of PM8280_{1/2} PMICs for measuring the on-chip die
temperature and external thermistors connected to the AMUX pins.

The measurements are collected by the primary PMIC PMK8280 from the
secondary PMICs PM8280_{1/2} and exposed over the PMK8280's VADC channels.
