    mediatek: fix nmbm configuration mismatch (Xiaomi AX3000t)
    
    This commit fixes nmbm configuration mismatch error on Xiaomi AX3000t
    with Winbond W25N01KVZEIR spi-nand:
    '''
    [    0.786783] NMBM configuration mismatch
    '''
    
    Root cause:
    1. U-Boot W25N01KV spi-nand driver ia compiled with 64B OOB size for the
       chip and store this size in the nmbm signature;
    2. Linux W25N01KV driver use 96B OOB.
    
    The change doesn't affect AX3000t variants with other spi-nand chips
    (ESMT, Foresee) because their Linux drivers use 64B OOB.
