    Implement the base infrastructure for libnvdimm PFN devices. Similar to
    BTT devices they take a namespace as a backing device and layer
    functionality on top. In this case the functionality is reserving space
    for an array of 'struct page' entries to be handed out through
    pfn_to_page(). For now this is just the basic libnvdimm-device-model for
    configuring the base PFN device.
    
    As the namespace claiming mechanism for PFN devices is mostly identical
    to BTT devices drivers/nvdimm/claim.c is created to house the common
    bits.
