[vijay.kilari at gmail.com]

From: Vijaya Kumar K <Vijaya.Kumar at cavium.com>

This patchset adds API for saving and restoring
of VGICv3 registers to support live migration with new vgic feature.
This API definition is as per draft version of VGICv3 specification
https://lists.cs.columbia.edu/pipermail/kvmarm/2016-May/020355.html

To test live migration with QEMU, the QEMU patches will
be posted soon.

The patch 3 & 4 are picked from the Pavel's previous implementation.
