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.

ACPI: HMAT: attach a device for each soft-reserved range
The hmem enabling in commit cf8741ac57ed ("ACPI: NUMA: HMAT: Register
"soft reserved" memory as an "hmem" device") only registered ranges to the
hmem driver for each soft-reservation that also appeared in the HMAT.
While this is meant to encourage platform firmware to "do the right thing"
and publish an HMAT, the corollary is that platforms that fail to publish
an accurate HMAT will strand memory from Linux usage. Additionally, the
"efi_fake_mem" kernel command line option enabling will strand memory by
default without an HMAT.
Arrange for "soft reserved" memory that goes unclaimed by HMAT entries to
be published as raw resource ranges for the hmem driver to consume.
Include a module parameter to disable either this fallback behavior, or
the hmat enabling from creating hmem devices. The module parameter
requires the hmem device enabling to have unique name in the module
namespace: "device_hmem".
The driver depends on the architecture providing phys_to_target_node()
which is only x86 via numa_meminfo() and arm64 via a generic memblock
implementation.

ACPI: HMAT: refactor hmat_register_target_device to hmem_register_device
In preparation for exposing "Soft Reserved" memory ranges without an HMAT,
move the hmem device registration to its own compilation unit and make the
implementation generic.
The generic implementation drops usage acpi_map_pxm_to_online_node() that
was translating ACPI proximity domain values and instead relies on
numa_map_to_online_node() to determine the numa node for the device.
