psu-ng: Add in detection of fan faults
If the FANS bit in the STATUS_WORD turns on (A fan or airflow fault or
warning has occurred), set a fan fault indicator in the power supply
object. During analysis of the power supplies, if a fan fault has
occurred, prioritize that over a temperature fault, include the
STATUS_TEMPERATURE and STATUS_FANS_1_2 command responses in the error
created. Call out the power supply with the fault.
Tested:
Verify no faults detected or logged on real hardware (Rainier 2S4U).
Simulate fan 1 fault on Rainier 2S2U, 110015FF PEL created.
