powerpc/powernv: Fix OPAL cfgread/cfgwrite error handling

Description

powerpc/powernv: Fix OPAL cfgread/cfgwrite error handling

Freeze clearing needs to heppen any time OPAL reads return either an error
(except OPAL_HARDWARE), AND any time it returns 0xff for all bytes.

For cfgwrite, any error that's not OPAL_HARDWARE should be cleaned up.
