Hi,
I have prototyped Live migration with GICv3.
For this I have made following changes
1) Save and Restore of GICv3 registers in QEMU.
- For GICv2, QEMU is saving/restoring GICD, GICC registers. For GICv3,
we have to save/restore GICD,

Currently we initialize all the possible GIC frame addresses in one

As this gets confusing when adding another VGIC model later, lets
move these initializations into

Contrary to other GICv3 interrupts, LPIs do not have an active state
by virtue of being edge-triggered only (they only have a pending state).
Given this, there is no point trying to deactivate them, and we can
