The OCXL specification supports distributing acTags amongst different
AFUs and functions on the link. The platform-specific acTag range for the
link is obtained using the OCXL provider services and then assigned to the
host function based on implementation. For cxlflash devices only a single
function per host is expected and thus the entire range is assigned.
