commit 0128d860a0724514256e1a31e24f0515a7b7bd0e

    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.
