This patch add a new mmap implementaion for hns, subsequent new mmap types will be implemented using this method.

Changes in v4: ============== - Replace rdma_user_mmap_entry with hns_user_mmap_entry. - Use rdma_user_mmap_entry_insert_range() to achieve compatibility with legacy mode and always keep the mmap routine in new mode.
