hwmon: (aquacomputer_d5next) Add support for Aquacomputer Farbwerk 360

Extend aquacomputer_d5next driver to expose hardware temperature sensors of the Aquacomputer Farbwerk 360 RGB controller, which communicates through a proprietary USB HID protocol.

Four temperature sensors are available. Additionally, serial number and firmware version are exposed through debugfs.

This driver has been tested on x86_64.

Changes in v4:
- Fix formatting issues

Changes in v3:
- Reformatted channel info and array holding device names
- Shortened prefix of methods and structs to aqc

Changes in v2:
- Extended the existing aquacomputer_d5next driver instead of creating a new one and extended docs
- Moved asm include to the end
- Report ENODATA if sensor is disconnected instead of 0 degrees

+This driver exposes hardware sensors of listed Aquacomputer devices, which
