configurations: yosemite4: set fail safe percent to 80% for Fan fail

Set fail safe percent to 80% for fan sensors so that pid-control service
would set fan PWM to 80% when one of the fan failed.

Note: Need to apply Gerrit 67566 before adding this change.

Tested:
Tested with patch of Gerrit 67566 and checked that the fan PWM would be
set to 80% when one fan failed.
