[arm-allstar] Support for RPI POE hat plus

[Patrick Perdue]

Hi Dave:

I am using two nodes powered by PoE Plus boards. One has nothing 
connected to USB, and the other has a sound fob set up in a radio-less 
configuration.

There's nothing to do, really, unless you want to change the condition 
under which the fan on the PoE board spins.

I find the default fan threshold to be overly aggressive.

So I added the following lines to the bottom of /boot/config.txt, then 
restarted the Pi.

# PoE Hat Fan Speeds
dtparam=poe_fan_temp0=50000
dtparam=poe_fan_temp1=60000
dtparam=poe_fan_temp2=70000
dtparam=poe_fan_temp3=80000


By default, the PoE and PoE Plus fan, a whiny little thing, will turn on 
at 40 degrees C no matter what. If the Pi drops to 39 C for a minute, 
then back up to 40, on it goes, on and off all day long.

This will set it up so the lowest fan speed is used at 50 degrees c, 
faster at 60, 70, and the highest at 80.


HTH.
