Handle new UCD90160 MFR_STATUS sysfs location

The 4.13 UCD90160 device driver moved the sysfs location
of the mfr_status register from
  /sys/kernel/debug/ucd9000.0/mfr_status
to
  /sys/kernel/debug/pmbus/hwmonN/ucd90160/mfr_status

The PMBus class can already handle this, just need to
change the enum to tell it where to look.

MFR_STATUS is only read when collecting metadata
on fails.
