Subject: [PATCH] arm64: dts: qcom: pm8150x: add thermal alarms and thermal
 zones

Add temperature alarm and thermal zone configuration to all three
pm8150 instances. Configuration is largely based on the msm-4.19 tree.
These alarms use main adc of the pmic. Separate temperature adc is not
supported yet.
