- Introduce a 'struct cxl_region' object with support for provisioning
and assembling persistent memory regions.
- Introduce alloc_free_mem_region() to accompany the existing
request_free_mem_region() as a method to allocate physical memory
capacity out of an existing resource.
- Export insert_resource_expand_to_fit() for the CXL subsystem to
late-publish CXL platform windows in iomem_resource.
- Add a polled mode PCI DOE (Data Object Exchange) driver service and
use it in cxl_pci to retrieve the CDAT (Coherent Device Attribute
Table).
