meta-quanta: runbmc-nuvoton: pid: enable PID to control FAN tach for RunBMC
Enable phosphor-pid-control to control FAN tach according eight temperature sensors.
There are six FANs in RunBMC and all controlled by PWM1, thus we only define one fan type sensor in .json file.
Consider FAN tach might be stopped then cause RunBMC sever hang, FAN tach will turn into full speed if swampd daemon dead unexpected.
