Splitting the dtsi part from [1] and sending it again.

Add tzts1~5 and tztsABB from thermal sensor in SoC for
another get temperatrue. They don't need to thermal throttle.
And we bind coolers for thermal zone nodes of cpu_thermal.

  arm64: dts: mt8183: add thermal zone node
  arm64: dts: mt8183: add dynamic power coefficients
  arm64: dts: mt8183: Add #cooling-cells to CPU nodes

From: Matthias Kaehlcke <mka@chromium.org>

Add SoC temperature threshold at 68°C and target at 80°C.
Add trip points and cooling maps for big and litter clusters.
