The only references to the offending cooling-{min|max}-state are located 
in a few DTS files. Assuming they are obsolete, may I simply drop them?

$ git grep "cooling-.*-state"

arch/arm64/boot/dts/amlogic/meson-g12b-bananapi.dtsi: cooling-min-state = <0>;
arch/arm64/boot/dts/amlogic/meson-g12b-bananapi.dtsi: cooling-max-state = <3>;
