Subject: [PATCH 12/15] arm64: kvm: Compile remaining hyp/ files for both VHE/nVHE

This patch is part of a series which builds KVM's non-VHE hyp code separately
from VHE and the rest of the kernel.

The following files in hyp/ contain only code shared by VHE/nVHE:
  vgic-v3-sr.c, aarch32.c, vgic-v2-cpuif-proxy.c, entry.S, fpsimd.S
Compile them under both configurations. Deletions in image-vars.h reflect
eliminated dependencies of nVHE code on the rest of the kernel.
