cxl/region: Add a 'uuid' attribute
The process of provisioning a region involves triggering the creation of a new region object, pouring in the configuration, and then binding that configured object to the region driver to start its operation. For persistent memory regions the CXL specification mandates that it identified by a uuid. Add an ABI for userspace to specify a region's uuid.
