[PULL 10/15] s390x/s390-skeys: prepare for memory devices

[David Hildenbrand]

With memory devices, we will have storage keys for memory that
exceeds the initial ram size.

The TODO already states that current handling is subopimal,
but we won't worry about improving that (TCG-only) thing for now.
