amd/cimx: fix sb(8|9)00 NULL type redefine

It is inappropriate for chipset code to be redefining
    types -- especially NULL to a non-pointer type. There's
    only one non-straight forward change. A condition
    being checked was '!ptr_type == NULL' (0 as int). That
    check is actually 'ptr_type != NULL'.
