Aneesh Kumar K.V 7b88bda376 mm/demotion/dax/kmem: set node's abstract distance to MEMTIER_DEFAULT_DAX_ADISTANCE 
By default, all nodes are assigned to the default memory tier which is the
memory tier designated for nodes with DRAM

Set dax kmem device node's tier to slower memory tier by assigning
abstract distance to MEMTIER_DEFAULT_DAX_ADISTANCE.  Low-level drivers
like papr_scm or ACPI NFIT can initialize memory device type to a more
accurate value based on device tree details or HMAT.  If the kernel
doesn't find the memory type initialized, a default slower memory type is
assigned by the kmem driver.

[aneesh.kumar@linux.ibm.com: assign correct memory type for multiple dax devices with the same node affinity]
