This patch series is about enabling CXL-Type3 capability on Arm reference
design platform.

* Designated 8GB address space is reserved and configured for using as extended
  CXL memory.
* During PCIe enumeration process, a CXL device with DOE capability is looked
  for. Once discovered, using DOE method CDAT information is fetched and
  details like CXL device memory range, memory type collected.
* Thereafter using a registered notifier, SRAT and HMAT tables are updated with
  remote CXL memory information.

These additions will enable CXL.Memory device to be used as memory expander on
Arm Reference Design platform.
