target-ppc: Convert ppc cpu savevm to VMStateDescription

Browse source 
The savevm code for the powerpc cpu emulation is currently based around
the old register_savevm() rather than register_vmstate() method.  It's also
rather broken, missing some important state on some CPU models.

This patch completely rewrites the savevm for target-ppc, using the new
VMStateDescription approach.  Exactly what needs to be saved in what
configurations has been more carefully examined, too.  This introduces a
new version (5) of the cpu save format.  The old load function is retained
to support version 4 images.
