configurations: yosemite4: Adjust fan speed UNC setting and fan duty

Summary:
1. Set UNC value based on the fan speed at PWM 85% and add 5%
hysteresis mechanism for them.
 - Adjust UNC of inlet fan speed from 15730 to 13825 rpm.
 - Update 691 rpm for inlet UNC fan speed.
 - Adjust UNC of outlet fan speed from 15840 to 12400 rpm.
 - Update 620 rpm for outlet UNC fan speed.
2. When one fan failed, fan duty is set to 100%.
3. When one slot is unplugged during service time, fan duty
is set to 100%.
(based on thermal team's requirements)

To prevent continuous UNC assertion/deassertion
when the PWM is at 100% due to fan speed fluctuation.

Tested:
- Check the WarningHigh threshold of the fan boards
- Check if many assert/deassert SEL when pwm 100%
