This implements "OPAL V4". I posted Linux patches and wrote up an
intro here

  https://lists.ozlabs.org/pipermail/linuxppc-dev/2020-May/210032.html

This require a about 20 previous patches that I've posted over the
past couple of weeks, some with slight changes, so don't try to
apply them. Anyone interested ping me offline and I can put up a git
tree somewhere.

I didn't want to repost a vast series when it's really these last
few that are the interesting ones.

Forgive the lack of opal-api docs for now, I've been chopping and
changing things a bit, I'll do them at some point soon.

Next features in the pipe are a machine check driver and cpu idle
driver for OPAL, but I'll stop at this point so it's more digestable.

Thanks,
Nick
