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. Reviewed-by: Daniel Henrique Barboza <danielhb413@gmail.com> Signed-off-by: Cédric Le Goater <clg@kaod.org>
