Admittedly this is somewhat of a corner case. Actually I tried to keep
as much code common (in vgic.c) as possible, and it was possible without
much pain for GRP_ADDR and kvm_vgic_addr.
Also I consider this call part of the switching and connecting
functionality of the VGIC.
Looking at the code again I think I had it in -emul.c before, but
decided to move it back for some reason (probably some other code
dependency which needed to be exposed). So unless I find some time ;-)
and a good reason to move it I tend to keep it here.

Cheers,
Andre.
