There's a subtle different here, which is that this final kernel_entry
call used to be in the #else clause, and so emitted for the NONSEC ||
VIRT case. So if the _do_nonsec_entry call were to fail (not currently
possible) and return you'd end up trying again via the sec path.

I'm not sure that's a bad thing, but it is a difference so it'd be good
to know it was a deliberate choice (or not).
