target/ppc, spapr: Move VPA information to machine_data

Browse source 
CPUPPCState currently contains a number of fields containing the state of
the VPA.  The VPA is a PAPR specific concept covering several guest/host
shared memory areas used to communicate some information with the
hypervisor.

As a PAPR concept this is really machine specific information, although it
is per-cpu, so it doesn't really belong in the core CPU state structure.

There's also other information that's per-cpu, but platform/machine
specific.  So create a (void *)machine_data in PowerPCCPU which can be
used by the machine to locate per-cpu data.  Intialization, lifetime and
cleanup of machine_data is entirely up to the machine type.
