Extend aquacomputer_d5next driver to expose hardware temperature sensors
and fans of the Aquacomputer Quadro fan controller, which communicates
through a proprietary USB HID protocol. Implemented by Jack Doan [1].
Four temperature sensors and PWM controllable fans are available. The
liquid flow sensor is also exposed, implemented by Leonard Anderweit [2].
Additionally, serial number, firmware version and power-on count are
exposed through debugfs.
This driver has been tested on x86_64.
