I think until we have the whole SEV situation sorted out, it's best
to leave it as-is.

Leaving the dsb in there shouldn't cause a problem for a v6+v6k+v7
kernel, it just means we're wasting a few cycles stalling the
instruction pipeline while the dsb completes, which we don't really
need to do on v6.
