libnvdimm: allow a platform to force enable label support
Platforms like QEMU-KVM implement an NFIT table and label DSMs. However, since that environment does not define an aliased configuration, the labels are currently ignored and the kernel registers a single full-sized pmem-namespace per region. Now that the kernel supports sub-divisions of pmem regions the labels have a purpose. Arrange for the labels to be honored when we find an existing / valid namespace index block.
