xive: Add calls to save/restore the queues and VPs HW state
To be able to support migration of guests using the XIVE native
exploitation mode, (where the queue is effectively owned by the
guest), KVM needs to be able to save and restore the HW-modified
fields of the queue, such as the current queue producer pointer and
generation bit, and to retrieve the modified thread context registers
of the VP from the NVT structure : the VP interrupt pending bits.
However, there is no need to set back the NVT structure on P9. P10
should be the same.
Based on previous work from BenH.
