ndctl binaries, v66 and older, mistakenly require the ndbus to have
unique names. If not while enumerating the bus in userspace it drops bus
with similar names. This results in us not listing devices beneath the
bus.

Remove the direct dependency on of_node_to_nid() by using dev_to_node()
instead. Any DT platform device will have its NUMA node id set when the
device is created.
With this, commit 291717b6fbdb ("libnvdimm, of_pmem: workaround OF_NUMA=n
build error") can be reverted.

This patch adds peliminary device-tree bindings for persistent memory
regions. The driver registers a libnvdimm bus for each pmem-region
node and each address range under the node is converted to a region
within that bus.
