KVM: arm64: nv: Program host's VNCR_EL2 to the fixmap address

Since we now have a way to map the guest's VNCR_EL2 on the host,
we can point the host's VNCR_EL2 to it and go full circle!

Note that we unconditionally assign the fixmap to VNCR_EL2,
irrespective of the guest's version being mapped or not. We want
to take a fault on first access, so the fixmap either contains
something guranteed to be either invalid or a guest mapping.
