    ath79: fix longdata-aps256 wan port to work in factory bootloader
    
    In first commit I successfully bring WAN port into ethernet switch,
    without realizing that I was using custom bootloader. But if using
    original bootloader it do not works. WAN port in original bootloader
    is tied to using its own GMAC.
    
    This fix is made so this firmware will be compatible with orignal
    bootloader, so the user can directly flash from stock firmware without
    changing anything.
