Subject: [PATCH] hwmon: (aquacomputer_d5next) Move device-specific data into struct aqc_data
As preparation for adding support for more devices in upcoming patches,
move device-specific data, such as number of fans, temperature sensors,
register offsets etc. to struct aqc_data. This is made possible by
the fact that the supported Aquacomputer devices share the same layouts
of sensor substructures. This allows aqc_raw_event() and others to stay
general and not be cluttered with similar loops for each device.
