video: tegra: nvmap: remove obsolete NvMap API

remove obsolete NvMap API nvmap_mmap/_munmap/_kmap/_kunmap,
nvmap_sg_table/_free_sg_table/_set_host_private/_get_host_private,
nvmap_flush_deferred_cache/duplicate_handle_user_id and
nvmap_get_handle_user_id/_put_handle_user_id.
remove unused macros as well from public header.
