Subject: [PATCH net-next 4/6] net: stmmac: make in-band AN mode parsing is supported for non-DT

Not all platform uses DT, so phylink_parse_mode() will skip in-band setup
of pl->supported and pl->link_config.advertising entirely. So, we add the
setting of ovr_an_inband flag to make it works for non-DT platform.
