[PATCH v2] ARM: imx: imx8mn-*-evk: use DM settings for PHY configuration

[Heiko Thiery]

With the correct settings described in the device-tree the PHY settings
in the board init are no longer required. The values are taken from the
linux device tree.

v2:
 - remove phy-reset-gpios node (thanks to Michael)
    When using DM_ETH_PHY the reset-gpios from the phy is used
