    ramips: Add Xiaomi Mi Router 4A 100M International
    
    The international version of Mi Router 4A 100M is physically
    identical to the non-international one, but appears to be
    using a different partitioning scheme with the "overlay"
    partition being 2MiB in size instead of 1MiB. This means
    the following "firmware" partition starts at a different
    address and the DTS needs to be adjusted for the firmware
    to work.
