target-ppc: Synchronize VPA state with KVM
For PAPR guests, KVM tracks the various areas registered with the
H_REGISTER_VPA hypercall. For full emulation, of course, these are tracked
within qemu. At present these values are not synchronized. This is a
problem for reset (qemu's reset of the VPA address is not pushed to KVM)
and will also be a problem for savevm / migration.
The kernel now supports accessing the VPA state via the ONE_REG interface,
this patch adds code to qemu to use that interface to keep the qemu and
KVM ideas of the VPA state synchronized.
