package/openpowerlink: properly handle legacy options

Commit "b1063a0136 package/openpowerlink: bump to v2.2.2" tried to add
legacy handling but the new symbols are part of a choice, and Kconfig
does not enforce the select of a option from a choice.

Update the legacy entry for 2016.02, following the example described in
the beginning of the file.
