libnvdimm, of_pmem: workaround OF_NUMA=n build error
Stephen reports that an x86 allmodconfig build fails to build the of_pmem driver due to a missing definition of of_node_to_nid(). That helper is currently only exported in the OF_NUMA=y case. In other cases, ppc and sparc, it is a weak symbol, and outside of those platforms it is a static inline. Until an OF_NUMA=n configuration can reliably support usage of of_node_to_nid() in modules across architectures, mark this driver as 'bool' instead of 'tristate'.
