hwmon: (aquacomputer_d5next) Add support for Aquacomputer High Flow USB and MPS Flow
Extend aquacomputer_d5next driver to expose various hardware sensors of the Aquacomputer High Flow USB flow sensor, which communicates through a proprietary USB HID protocol. This commit also adds support for the sensors of the MPS Flow devices, as they have the same USB product ID and sensor layouts. Implemented by Leonard Anderweit [1]. Internal and external temp sensor readings are available, along with the flow sensor. Additionally, serial number and firmware version are exposed through debugfs.

The High Flow USB exposes an internal and external temperature sensor, and a flow meter.
|

|

The MPS Flow devices expose the same entries as the High Flow USB because they have

the same USB product ID and report sensors equivalently.

Depending on the device, not all sysfs and debugfs entries will be available.
|

Writing to virtual temperature sensors is not currently supported.
