Merged to master as of cb16e55a234b91fd42112904cff15094fbae680d. I'm not sure if we should backport this to stable@ though? Probably should?

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.
