KVM: arm/arm64: Rename vgic_attr_regs_access to vgic_attr_regs_access_v2
Just a rename so we can implement a v3-specific function later. We take the chance to get rid of the V2/V3 ops comments as well. No functional change. Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org> Reviewed-by: Eric Auger <eric.auger@redhat.com>
