arm64: dts: rockchip: Enable automatic fan control on Turing RK1

Browse Source 
This patch adds thermal trip points and cooling maps to the Turing RK1
in order to enable automatic control of the external PWM fan. The fan is
not active below 45C, as the heatsink alone can generally keep the chip
in this temperature region at idle load. This cooling profile errs on
the side of quietness, since the RK1 is commonly deployed in a Turing
Pi 2 clusterboard alongside three others, with additional cooling
provided at the chassis level.
