meta-ethanolx: Add PID control for fans
Add support for dynamic fan RPM control based on the values from
temperature sensors.
Control is based on PIDs and is splitted to 3 thermal zones:
Zone 1:
- CPU0 SB-TSI temp with a setpoint 60.0 C
- P0 FAN
Zone 2:
- CPU1 SB-TSI temp with a setpoint 60.0 C
- P1 FAN
Zone 3:
- All LM75A sensors on board with a setpoint 35.0 C
- SYS FAN1 - SYS FAN6
