Subject: [PATCH] arm64: dts: qcom: ipq8074: add critical thermal trips

According to bindings, thermal zones must have associated trips as well.
Since we currently dont have CPUFreq support and thus no passive cooling
lets start by defining critical trips to protect the devices against
severe overheating.
