commit 1caa71a7a600f7781ce05ef1e84701c459653663 upstream.
When reworking the vgic locking, the vgic distributor registration
got simplified, which was a very good cleanup. But just a tad too
radical, as we now register the *native* vgic only, ignoring the
GICv2-on-GICv3 that allows pre-historic VMs (or so I thought)
to run.
As it turns out, QEMU still defaults to GICv2 in some cases, and
this breaks Nathan's setup!
Fix it by propagating the *requested* vgic type rather than the
host's version.
