hwmon: (aquacomputer_d5next) Add support for Aquacomputer Poweradjust 3

Extend aquacomputer_d5next driver to expose the temp sensor of the
Aquacomputer Poweradjust 3 fan controller, which communicates
through a proprietary USB HID protocol.

The Poweradjust 3 is not currently known to expose firmware version
and serial number, so don't create debugfs entries if their values
can't be retrieved.

Tested by a user on Github [1].
