mtd: nand: hisi504: rely on generic DT parsing done in nand_scan_ident()
The core now takes care of parsing generic DT properties in nand_scan_ident() when nand_set_flash_node() has been called. Rely on this initialization instead of calling of_get_nand_xxx() manually. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com>
