ppc/spapr: remove deprecated machine pseries-2.7

Commit 1392617d3576 intended to tag pseries-2.1 - 2.11 machines as
deprecated with reasons mentioned in its commit log.
Removing pseries-2.7 specific code with this patch for now.

While at it, also remove pre-2.8-migration and pci/mmio hacks introduced
for backward compatibility.
