    armv4: add dcache policiy enumeration
    
    Some mainboards (nyans) are using architecture specific references
    in the device tree. However, if one is to include the static
    device tree in bootblock which doesn't have the value then the
    build will break. Duplicate the enumeration from armv7 even though
    the values aren't used at runtime.
