[v4,00/10] hw/cxl: CXL emulation cleanups and minor fixes for upstream

Message

Since V3:
- Rebased on upstream today.
- Refreshed DSDT.cxl due to changes upstream.
- Picked up tags from Gregory.

A small collection of misc fixes and tidying up pulled out from various
series. I've pulled this to the top of my queue of CXL related work
as they stand fine on their own and it will reduce the noise in
the larger patch sets if these go upstream first.

Gregory's patches were posted as part of his work on adding volatile support.
https://lore.kernel.org/linux-cxl/[e-mail]/
https://lore.kernel.org/linux-cxl/[e-mail]/
I might propose this for upstream inclusion this cycle, but testing is
currently limited by lack of suitable kernel support.

Ira's patches were part of his event injection series.
https://lore.kernel.org/linux-cxl/[e-mail]/
Intent is to propose for upstream the rest of that series shortly after
some minor changes from earlier review.

My five patches have not previously been posted before this series.
