Seems the trips & cooling-maps are required as described in thermal.txt

For the soc_thermal zone it's esy to add a cooling map with the CPU
and cooling devices, but for the ddr_thermal, no idea if we can use the
CPUs within 2 cooling maps.

I would add a blank line between the zones, same for other files.
