Subject: [PATCH net-next v2 4/6] net: phylink: unset ovr_an_inband if fixed-link is selected

If "fixed-link" DT or ACPI _DSD subnode is selected, it should take
precedence over the value of ovr_an_inband passed by MAC driver.

Fixes: ab39385021d1 ("net: phylink: make phylink_parse_mode() support non-DT platform")
