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].

Supported devices:

@ -20,6 +21,10 @@ Description
This driver exposes hardware sensors of listed Aquacomputer devices, which
communicate through proprietary USB HID protocols.
The Aquaero devices expose eight temperature sensors, eight virtual temperature
sensors and two flow senors. The fans expose their speed (in RPM), power,
voltage and current.
For the D5 Next pump, available sensors are pump and fan speed, power, voltage
and current, as well as coolant temperature and eight virtual temp sensors. Also
available through debugfs are the serial number, firmware version and power-on
