net: phy: fix reading fixed phy status
With the switch to phy_resolve_aneg_linkmode() we don't read from the
chip any longer what is advertised but use phydev->advertising directly.
For a fixed phy however this bitmap is empty so far, what results in
no common mode being found. This breaks DSA. Fix this by advertising
everything that is supported. For a normal phy this done by phy_probe().
