In the initial implementation a number of PMBUS_x_WARN_LIMITs were
mapped to MFR fields. This was incorrect as these MFR limits reflect the
rated limit as opposed to a limit which will generate warning. Instead
return -ENXIO like we were already doing for other WARN_LIMITs.
Subsequently these rated limits have been exposed generically as new
fields in the sysfs ABI so the values are still available.

Notes:
Changes in v2:
- Reworked to remove the mapping of warning limits to rated limits.
