    brcm2708: add compatible strings
    
    This patch adds the compatible string for the various RPIs from
    4.14 upstream.
    
    Note: The 4.14 upstream does not include the compute modules.
    If the CM* would just house the SoC, it could in theory use the
    "raw" chip compatible string. However, these CM boards also come
    with RAM and eMMC. So they have to have a proper comaptible.
    
    For now, "raspberrypi,compute-module-{1|3}" will be good enough.
    
    Note2: The original CM was renamed to CM1 when CM3 was released.
