Re: [PATCH RFC] hw/cxl: type 3 devices can now present volatile or persistent memory

[Gregory Price]

I've pushed 5 new commits to this branch here (@Jonathan I've also made
a merge request to pull them into your branch).

https://gitlab.com/gourry.memverge/qemu/-/commits/cxl-2022-10-09

They're built on top of Jonathan's extensions for the CDAT since the
CDAT has memory region relevant entries and trying to do this separate
would be unwise.

1/5: PCI_CLASS_MEMORY_CXL patch
2/5: CXL_CAPACITY_MULTIPLIER pullout patch (@Davidlohr request)
3/5: Generalizes CDATDsmas intialization ahead of multi-region
4/5: Multi-region support w/ backward compatibility
     * Requires extra eyes for CDAT and Read/Write Change Validation*
5/5: Test and documentation update
