arm64: dts: rockchip: Add PWM fan to Radxa ROCK 3B
The ROCK 3B has a 2-pin fan header powered from vcc5v0_sys and
switched by a MOSFET driven from PWM8 (pwm8m0 pins). Enable the PWM
controller, describe the fan as a pwm-fan cooling device and add
active trip points to the CPU thermal zone:
- 50 C: fan at 25%
- 60 C: fan at 50-75%
- 70 C: fan at 100%
each with 5 C hysteresis. The existing passive and critical trip
points are left unchanged.
