libnvdimm, region: move region-mapping input-paramters to nd_mapping_desc
Before we add more libnvdimm-private fields to nd_mapping make it clear which parameters are input vs libnvdimm internals. Use struct nd_mapping_desc instead of struct nd_mapping in nd_region_desc and make struct nd_mapping private to libnvdimm. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
