[PATCH 2/2] arm64: dts: qcom: monaco-pmics: Enable PMIC MBG thermal monitor

[Sachin Gupta <sachin.gupta@oss.qualcomm.com>]

Monaco boards use PM8620AU PMIC instances that expose MBG thermal monitor
blocks handled by the existing qcom-spmi-mbg-tm driver.

Add MBG temperature-sensor nodes for the PMIC instances and wire them into
dedicated thermal zones with passive trips, so PMIC die temperature
monitoring is available through the thermal framework.
