    This function sets the PB divider, the Flash Wait States, and the DRM
    /wait states to the optimum value.  It also enables the cacheability for
    the K0 segment.  It could has side effects of possibly alter the pre-fetch
    buffer and cache.  It sets the RAM wait states to 0.  Other than
    the SYS_FREQ, this takes these parameters.  The top 3 may be '|'ed

    SYS_CFG_PB_BUS (configures the PB bus from the system clock)
