    ramips: dts: rt3050: 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.
    
    This is behaviour of downstream driver as well, however I
    haven't observed bug reports about this SoC in the wild, so this
    commit's purpose is to align this chip with all other SoC's - MT7620
    were already using this arrangement.
    
    Fixes: 60fadae62b64 ("ramips: ethernet: ralink: move reset of the esw into the esw instead of fe")
