The intention is not to have a second definition, instead this should
enable the default value just for arm64. Thus I put it to
arch/arm64/Kconfig. Otherwise it would be enabled per default on all
archs.
We could have used select in config ARM64, but I tried to avoid using
select due to the dependency issue and instead implement this with
default-y/depends-on. Doing so it can be manually disabled too.
