mainboard/asus/kfsn4-dre: Enable W83793 fan controller
The Winbond W83793 fan controller is not automatically
configured correctly on power application, leading to
abnormal, and in some cases random, fan behaviour.
This commit enables the controller and sets sane default
values.
TEST: Booted mainboard and verified that the correct number
of fan speed sensors were visible from hwmon under Linux.
Also verified that, unlike before, the CPU fans were running
at a high enough speed to properly cool the CPUs. Verified
the 8 fan outputs under direct control of the W83793 device.
Verified voltage and temperature sensors and limits via output
of the 'sensors' command.
