ppc/spapr: remove deprecated machine pseries-2.3

Commit 1392617d3576 intended to tag pseries-2.1 - 2.11 machines as
deprecated with reasons mentioned in its commit log.
Removing pseries-2.3 specific code with this patch for now.

While at it, also remove the dynamic-reconfiguration option which was
introduced to disable it by default for legacy machines until pseries-2.3.
