    The DSU contains system control registers in the SCU and L3 logic to
    control the functionality of the cluster. If "DIRECT CONNECT" L3
    memory system variant is used, there won't be any L3 cache,
    snoop filter, and SCU logic present hence no system control register
    will be present. Hence check SCU presence before accessing DSU register
    for DSU_936184 errata.
