hw/intc: Initial implementation of vGICv3
This is the initial version of KVM-accelerated GICv3 support.
State load and save are not yet supported, live migration is
not possible.
In order to get correct class name in a simpler way, gicv3_class_name()
function is implemented, similar to gic_class_name().
