In preparation for registering device-dax instances for accessing EFI specific-purpose memory, arrange for the HMAT registration to occur later in the init process. Critically HMAT initialization needs to occur after e820__reserve_resources_late() which is the point at which the iomem resource tree is populated with "Application Reserved" (IORES_DESC_APPLICATION_RESERVED). e820__reserve_resources_late() happens at subsys_initcall time.
