FROMLIST: arm64: dts: qcom: monaco-pmics: Add ADC support for PMM8620AU

Add ADC nodes for PMM8620AU PMIC instances (SID 0 and SID 2)
present on the Monaco platform.

Each ADC node exposes the following ADC channels:
 - DIE_TEMP: PMIC die temperature channel
 - VPH_PWR: Battery/supply voltage channel
