dax/hmem: Move HMAT and Soft reservation probe initcall level In preparation for moving more filtering of "hmem" ranges into the dax_hmem.ko module, update the initcall levels. HMAT range registration moves to subsys_initcall() to be done before Soft Reservation probing, and Soft Reservation probing is moved to device_initcall() to be done before dax_hmem.ko initialization if it is built-in.

dax/hmem: Move hmem device registration to dax_hmem.ko In preparation for the CXL region driver to take over the responsibility of registering device-dax instances for CXL regions, move the registration of "hmem" devices to dax_hmem.ko. Previously the builtin component of this enabling (drivers/dax/hmem/device.o) would register platform devices for each address range and trigger the dax_hmem.ko module to load and attach device-dax instances to those devices. Now, the ranges are collected from the HMAT and EFI memory map walking, but the device creation is deferred. A new "hmem_platform" device is created which triggers dax_hmem.ko to load and register the platform devices.

dax: Cleanup extra dax_region references Now that free_dev_dax_id() internally manages the references it needs the extra references taken by the dax_region drivers are not needed.
