ARM: dts: sun8i-h3: Add thermal trip points/cooling maps

Browse source

This enables passive cooling by down-regulating CPU voltage
and frequency.

For trip points, I used a slightly lowered values from the BSP
code. The critical temperature of 110°C from BSP code seemed
like a lot, so I rounded it off to 100°C.

The critical trip point value is 30°C above the maximum recommended
ambient temperature (70°C) for the SoC from the datasheet, so there's
some headroom even at such a high ambient temperature.
