Erik Rosen 86c908d90f hwmon: (pmbus) Add new flag PMBUS_READ_STATUS_AFTER_FAILED_CHECK 
Some PMBus chips end up in an undefined state when trying to read an
unsupported register. For such chips, it is necessary to reset the
chip pmbus controller to a known state after a failed register check.
This can be done by reading a known register. By setting this flag the
driver will try to read the STATUS register after each failed
register check. This read may fail, but it will put the chip into a
known state.
