hwmon: (aquacomputer_d5next) Add support for Aquacomputer Octo

Browse Source 
Extend aquacomputer_d5next driver to expose hardware temperature sensors
and fans of the Aquacomputer Octo fan controller, which communicates
through a proprietary USB HID protocol.

Four temperature sensors and eight PWM controllable fans are available.
Additionally, serial number, firmware version and power-on count are
exposed through debugfs.

This driver has been tested on x86_64.

The Octo exposes four temperature sensors and eight PWM controllable fans, along
with their speed (in RPM), power, voltage and current.
The Farbwerk 360 exposes four temperature sensors. Depending on the device,
not all sysfs and debugfs entries will be available.

If you say yes here you get support for the Aquacomputer D5 Next
watercooling pump sensors.
If you say yes here you get support for sensors and fans of
the Aquacomputer D5 Next watercooling pump, Octo fan
controller and Farbwerk 360 RGB controller, where available.
This driver can also be built as a module. If so, the module
will be called aquacomputer_d5next.
