ppc/spapr: remove deprecated machine pseries-2.9

Commit 1392617d3576 intended to tag pseries-2.1 - 2.11 machines as
deprecated with reasons mentioned in its commit log.
Removing pseries-2.9 specific code with this patch for now.

While at it, also remove the pre-2.10 migration hacks which now become
obsolete.
