KVM: PPC: Book3S PR: Fix broken select due to misspelling

Commit 76d837a ("KVM: PPC: Book3S PR: Don't include SPAPR TCE code
on non-pseries platforms") added a reference to the globally undefined
symbol PPC_SERIES. Looking at the rest of the commit, PPC_PSERIES was
probably intended.

Change PPC_SERIES to PPC_PSERIES.

Discovered with the
https://github.com/ulfalizer/Kconfiglib/blob/master/examples/list_undefined.py
script.
