New spdk_ftl_conf parameter l2p_path, l2p_path defines location of existing pmem file or device to use as l2p table. ftl_dev_l2p_alloc now has two flows: 1. If l2p_path is set perform pmem_map_file (PMDK) of l2p_size on it 2. Else malloc l2p table as usual l2p_get/set will use atomic_load/store on both of those storage locations as PMDK pmem_memcpy family of functions is not thread safe.
