The only actual arm64 specific code in this driver is an open-
coded 128 bit MMIO write. On non-arm64 the same can be done

To avoid missing arm64 specific warnings that get introduced
in this driver, allow compile-testing on all 64-bit architectures.
The only actual arm64 specific code in this driver is an open-
coded 128 bit MMIO write. On non-arm64 the same can be done
using memcpy_toio. What I also noticed is that
