net: designware: fix PHY reset with DM_MDIO
The dw_eth_pdata is not accessible from the mdio device, it gets the mdio bus plat
leading to random sleeps (-10174464 on Odroid-HC4).
This moves the dw_mdio_reset function to a common one taking the ethernet
device as parameter and use it from the dw_mdio_reset and dm_mdio variant functions.
Fixes: 5160b4567c ("net: designware: add DM_MDIO support")
