powerpc/selftests: Add test for papr-sysparm

Browse source

Consistently testing system parameter access is a bit difficult by
nature -- the set of parameters available depends on the model and
system configuration, and updating a parameter should be considered a
destructive operation reserved for the admin.

So we validate some of the error paths and retrieve the SPLPAR
characteristics string, but not much else.
