cxl/mem: Register CXL memX devices
Create the /sys/bus/cxl hierarchy to enumerate:
* Memory Devices (per-endpoint control devices)
* Memory Address Space Devices (platform address ranges with
interleaving, performance, and persistence attributes)
* Memory Regions (active provisioned memory from an address space device
that is in use as System RAM or delegated to libnvdimm as Persistent
Memory regions).
For now, only the per-endpoint control devices are registered on the
'cxl' bus. However, going forward it will provide a mechanism to
coordinate cross-device interleave.
