PNOR: Restore RedundancyPriority on reset
This commit extends the functionality of the PNOR software updater by
preserving RedundancyPriority values through any kind of reset.
This is accomplished by storing priority values in serial files in
/var/lib/obmc/openpower-pnor-code-mgmt/ using the Cereal library. Each
time a priority value is modified, the value in the corresponding
version file is adjusted.
When the item updater resets, it reads back the priority values from
these files.
Resolves openbmc/openbmc#2040
