W83792D supports different FAN power on time. The FAN will power on one by one after 5VDD is
ready. (At sequence FAN6-2-3-1-4-5) Fan Divisor also determines the FAN power on time. Under
power-on-default setting(divisor = 2), to power on all FAN will take 71.5ms. If divisor is change, the
timing will be different.
