hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow Next
Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow Next flow sensor, which communicates through a proprietary USB HID protocol. The High Flow Next exposes +5V voltages, water quality, conductivity and flow readings. A temperature sensor can be connected to it, in which case it provides its reading and an estimation of the dissipated/absorbed power in the liquid cooling loop. Additionally, serial number and firmware version are exposed through debugfs. Registry offsets were discovered and tested by users on Github [1] [2].
