Prepare the pmem driver to consume PMEM namespaces emitted by regions of
an nvdimm_bus instance.  No functional change.

As LIBNVDIMM depends on PHYS_ADDR_T_64BIT, the driver can no
longer be enabled on pure 32-bit platforms. Is that intended?

Yes it was intentional.  It still allows 32-bit platforms with 64-bit
resource_size_t to compile. Do you otherwise have a 32-bit use case
for pmem?  I'm of course open to working through the changes to add
wider architecture support.
