arm64: dts: qcom: lemans-pmics: Enable PMIC MBG thermal monitor
Lemans boards use PM8654AU 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.
