The fans are capable of reporting a fault to the CPLD controller which
then reports it to the GXP SoC via PLREGS. This patch enables hwmon to
be able to report these failures up to the HOST OS.


This change is really completely unrelated to a CPLD or specific SoC.
The commit description is just confusing. It should simply state that
it documents the existing fanX_fault attribute.
