Subject: [PATCH] ARM: dts: qcom: add PMIC Glink ADC channel nodes for Sun
 boards

Add PMIC Glink ADC channel nodes for Sun MTP and QRD boards.
This exposes an interface for software to read PMIC charger ADC
channels for input current, charge current, and die temperature.
This is useful for PMICs connected via I2C which are only
accessible to charger firmware.
