Subject: [PATCH v7 5/5] arm64: dts: ipq8074: add thermal nodes

IPQ8074 has a tsens v2.3.0 peripheral which monitors
temperatures around the various subsystems on the
die.

So lets add the tsens and thermal zone nodes, passive
CPU cooling will come in later patches after CPU frequency
scaling is supported.
