openpower-software-manager: Support migration to ubifs
A ubiattach is the first step for any ubi operations. If this
service fails, it could be that the pnor chip is formatted
differently, as with the case of flashing it with pflash.
Enhance the service to:
Check if the chip is formatted as a ubi device.
If it's not, format it as ubi with a new ubiformat script.
Reattempt the attach.
This allows a pnor code update without the user having
to manually reformat the chip.
Closes openbmc/openbmc#1637
