I know there was some off-list suggestion to split this into a number
of patches, but to actually make that useful to anyone we'd actually
need to _also_ post up patches to make the driver probe / work without
these power domains.  ...and as per other discussions it's kinda
"lucky" that it happens to work without them and Bjorn wasn't
supportive of making this optional.

So I'd actually fold patch 6 into patch 5 and focus on getting the
"aoss_qmp_pd" landed sooner rather than later.

Keeping the "shutdown-ack" as a separate patch makes sense though
since the bindings currently list that as "optional" and I guess
things work OK w/out it.

Once patch #6 is folded into patch #5 feel free to add my Reviewed-by tag.
