net: stmmac: platform: Fix MDIO init for platforms without PHY
The current implementation of "stmmac_dt_phy" function initializes
the MDIO platform bus data, even in the absence of PHY. This fix
will skip MDIO initialization if there is no PHY present.
Fixes: 7437127 ("net: stmmac: Convert to phylink and remove phylib logic")
