Example patch for sys/arm64/arm64/identcpu.c 's sev instruction use

Beyond the release_aps use of SEV during boot
I found a SEV use in identcpus.c . So this is
a possible patch for that (for the same issue
of SEV not being timed relative to memory
updates).

I do not claim either patch has the optimal
form of dsb ??? instruction, just one that
seems (more then?) sufficient.
