Given that Ted seems to have lost interest in /dev/random patches, I
was hoping [1] could be taken via the arm64 tree instead. Without this
patch, I don't think we should expose the SMCCC RNG interface via
arch_get_random_seed(), given how insanely often it will be called in
that case.

Note that the KVM patch implements the opposite end of this interface,
and is not affected by [1] at all, so that can be taken at any time.
