David Gibson 80c33d343f pseries: Split CAS PVR negotiation out into a separate function
Guests of the qemu machine type go through a feature negotiation process
known as "client architecture support" (CAS) during early boot.  This does
a number of things, one of which is finding a CPU compatibility mode which
can be supported by both guest and host.

In fact the CPU negotiation is probably the single most complex part of the
CAS process, so this splits it out into a helper function.  We've recently
made some mistakes in maintaining backward compatibility for old machine
types here.  Splitting this out will also make it easier to fix this.

This also adds a possibly useful error message if the negotiation fails
(i.e. if there isn't a CPU mode that's suitable for both guest and host).
