ARM: imx: imx8mn-*-evk: use DM settings for PHY configuration

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.

The PHY latency settings are derived from the phy-mode property and the
voltage seetings are done via the regulator.
