When configuring PHY advertising with autoneg disabled, we lookd for an
exact linkmode to advertise and configure for the requested Speed and
Duplex, specially at or over 1G.

Using phy_caps_lookup allows us to build a list of the supported
linkmodes at that speed that we can advertise instead of the first mode
that matches.
