    ramips: mt7621-dts: remove ethsys node
    
    DT 'ethsys' node is being configured as a syscon
    to get access to reset and other registers in the
    'mediateķ,mt7621-eth' driver. Since the 'sysc' is also
    a syscon, provides the clock and also is virtually
    mapped from the same physical address 0x1e000000 we
    can just use 'sysc' as the phandle for the syscon in
    the ethernet node. Compatible string 'mediatek,mt7621-ethsys'
    of the node is not being used anywhere inside the kernel
    so, this node can be safely removed.
