Cédric Le Goater 835806f1f9 pnv/xive2: Add support for automatic save&restore 
The XIVE interrupt controller on P10 can automatically save and
restore the state of the interrupt registers under the internal NVP
structure representing the VCPU. This saves a costly store/load in
guest entries and exits.
