[][MT7986a: Fix pwm fan support and update example cooling strategies] [Description] Add pwm fan support to mt7986a example cooling strategies: over 125 : reboot 120~125 : notify to driver callback (if callback function is set) 115~120 : FAN 100% 85~115 : FAN 50% bellow 85 : FAN 0% You need to connect the 'pwm' pin of PWM FAN to 'PWM1' (GPIO22) pin on mt7986, and set 'status' properties of 'fan' node in the device tree to enable this.
