Move hmem/ earlier in the dax Makefile so that hmem_init() runs before dax_cxl. In addition, defer registration of the dax_cxl driver to a workqueue instead of using module_cxl_driver(). This ensures that dax_hmem has an opportunity to initialize and register its deferred callback and make ownership decisions before dax_cxl begins probing and claiming Soft Reserved ranges. Mark the dax_cxl driver as PROBE_PREFER_ASYNCHRONOUS so its probe runs out of line from other synchronous probing avoiding ordering dependencies while coordinating ownership decisions with dax_hmem.
