    mvebu: fix support for Marvell 8040 MACCHIATOBin
    
    Between kernels 4.20 and 5.0, a new variant of this board has been
    introduced ("Single Shot"), and the existing one has been renamed
    with the appendix "Double Shot". [1]
    This also adjusted the first compatible in the list:
    
    marvell,armada8040-mcbin -> marvell,armada8040-mcbin-doubleshot
    
    This patch updates the OpenWrt implementation of this device by
    adjusting the relevant references to that compatible (i.e., our
    board name).
    
    To still provide support for 4.19 with our setup, this adds a
    small patch to change the compatible there as well.
