    ath79: reduce config partition size for RE450 v1 and RE355 v1 to 0x20000
    
    Dump of content of my RE450 v1 showed, that there are valid data only
    up to 0x10420. Everything after is just 0xFF. This will also make
    partition table identical to qca9563_tplink_re450-v2.dts, which seems
    to be logical.
