I think it makes sense to also update the Kconfig symbol description for
CONFIG_ARM64_PTR_AUTH, since it currently only mentions userspace
support, but now the option also enables KVM guest support.

It's also worth mentioning that CONFIG_ARM64_VHE=y is required for guest
support.

Thanks,
Kristina
