net: stmmac: Fix case when PHY handle is not present
Some DT bindings do not have the PHY handle. Let's fallback to manually
discovery in case phylink_of_phy_connect() fails.
Changes from v1:
- Fixup comment style (Sergei)
Fixes: 74371272f97f ("net: stmmac: Convert to phylink and remove phylib logic")
