mtd: rawnand: meson: fix build error

Fixes the following build error:

drivers/mtd/nand/raw/meson_nand.c:244:59: error: initializer element is not a compile-time constant
static const struct nand_ecc_step_info axg_stepinfo[] = { axg_stepinfo_1024, axg_stepinfo_512 };
                                                          ^~~~~~~~~~~~~~~~~
