KVM: arm64: Enforce dependency on an ARMv8.4-aware toolchain
With the NV support of TLBI-range operations, KVM makes use of
instructions that are only supported by binutils versions >= 2.30.
This breaks the build for very old toolchains.
Make KVM support conditional on having ARMv8.4 support in the
assembler, side-stepping the issue.
