This patch converts the dart6ul ethernet support to DM_ETH and cleans up the legacy ethernet code. The clean up, more specifically: * moves the fec2 node and pin definition to the carrier board DTS since the phy associated with it is on the carrier board and not on the SoM; * add the reset pin associated to each phy; * separate the ethernet, mdio and reset pins of each fec so that they are easier to reference; * add clock properties to the phy nodes since they are connected to the 50Mhz ENET[12]_TX_CLK clock of the SoC; * remove CONFIG_BOARD_EARLY_INIT_F since the function is now empty.
