hwmon: (aquacomputer_d5next) Support sensors for Aquacomputer Aquaero
Add support for reading sensors of the Aquacomputer Aquaero 5/6 fan
controllers. These fan controllers supports 4 fans, 8 physical
temperature sensors, 8 virtual temperature sensors and 2 flow sensors.
Temperature and flow sensor reading implemented by Aleksa Savic [1] [2]
[3].
