PATCH 1/2 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.
