mxc_ocotp: Update redundancy banks for mx7ulp B0
On mx7ulp B0, beside bank 0 and 1, the fuse bank 9, 10, 28 are changed to Redundancy mode not ECC, so they can support to program different bits of a word in multiple times. Signed-off-by: Ye Li <ye.li@nxp.com> Signed-off-by: Peng Fan <peng.fan@nxp.com>
