arm/arm64: KVM: pass down user space provided GIC type into vGIC code

Browse Source 
With the introduction of a second emulated GIC model we need to let
userspace specify the GIC model to use for each VM. Pass the
userspace provided value down into the vGIC code and store it there
to differentiate later.
