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") Reported-by: Mark Kettenis <mark.kettenis@xs4all.nl> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
