commit 5ef01117b77648e24287d304cf016092069c730a

    ramips: dts: mt7628an: reset FE and ESW cores together
    
    Failing to do so will cause the DMA engine to not initialize properly
    and fail to forward packets between them, and in some cases will cause
    spurious transmission with size exceeding allowed packet size, causing a
    kernel panic.
