hwmon: (aquacomputer_d5next) Clear up macros and comments

Reorganize macro definitions into sections for each supported
device, with additional comments on their purpose. This should
make it easier to follow what report each offset is coming
from. Also, reformat per-device initializations in
aqc_probe() to organize them into sections (fan info,
temp sensors, other parameters and lastly labels).

No functional changes.
