arm64: dts: qcom: pm6350: add temp sensor and thermal zone config

Add temp-alarm device tree node and a default configuration for the
corresponding thermal zone for this PMIC. Temperatures are based on
downstream values, except for trip2 where 125°C is used instead of 145°C
due to limitations without a configured ADC.
