v5: Thanks to Michael Tsirkin for review
 - Use memory_region_size() instead of incorrect open coding.
   Add a precursor patch tidying up existing uses.

Depends on some of the fix series posted (mostly fuzz).
[PATCH 0/2]  hw/cxl: CDAT file handling fixes.
[PATCH v2 0/3] hw/cxl: Fix decoder commit and uncommit handlin
[PATCH 0/3] docs/cxl: Gathering of fixes for 8.0 CXL docs.

Now kernel support is in place, lets catch up with the emulation
of volatile memory on CXL type 3.

Original cover letter with minor updates.

This patches provides 2 features to the CXL Type-3 Device:
    1) Volatile Memory Region Support
    2) Multi-Region support (1 Volatile, 1 Persistent)

Summary of Changes per-commit:
1) Whitespace updates to docs and tests
2) Refactor CDAT DSMAS Initialization for multi-region initialization
   Multi-Region and Volatile Memory support for CXL Type-3 Devices
   Test and Documentation updates

The final patch in this series makes 6 major changes to the type-3
device in order to implement multi-region and volatile region support
    1) The HostMemoryBackend [hostmem] has been replaced by two
       [hostvmem] and [hostpmem] to store volatile and persistent memory
       respectively
    2) The single AddressSpace has been replaced by two AddressSpaces
       [hostvmem_as] and [hostpmem_as] to map respective memdevs.
    3) Each memory region size and total region are stored separately
    4) The CDAT and DVSEC memory map entries have been updated:
       a) if vmem is present, vmem is mapped at DPA(0)
       b) if pmem is present
          i)  and vmem is present, pmem is mapped at DPA(vmem->size)
          ii) else, pmem is mapped at DPA(0)
       c) partitioning of pmem is not supported in this patch set but
          has been discussed and this design should suffice.
    5) Read/Write functions have been updated to access AddressSpaces
       according to the mapping described in #4.  Access to the
       persistent address space is calculated by (dpa-vmem_len)
    6) cxl-mailbox has been updated to report the respective size of
       volatile and persistent memory region.
