    opal-prd: Insert powernv_flash module
    
    Explictly load powernv_flash module on BMC based system so that we are sure
    that flash device is created before starting opal-prd daemon.
    
    Note that I have replaced pnor_available() check with is_fsp_system(). As we
    want to load module on BMC system only. Also pnor_init has enough logic to
    detect flash device. Hence pnor_available() becomes redundant check.
