[U-Boot] [PATCH 3/6] ARM: imx: vining2000: Convert to ethernet DM

[Marek Vasut]

Convert the board to ethernet DM support. Adjust board file accordingly,
as the board_eth_init() contains custom clock configuration required for
this board to work. Furthermore, enable FEC1 clock to make FEC1 work as
well.
