[PATCH] ARM: imx6: DHCOM i.MX6 PDK: Convert to DM_ETH

[Harald Seiler]

Use DM_ETH instead of legacy networking.

Notes:
    I am unsure whether I converted 'enough' of the board_eth_init()
    function to DM.  I think the reset GPIO in particular could be handled
    by the DM driver if I add the following to the device-tree (did not try
    it yet):
    
    	phy-reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
    	phy-reset-duration = <1>;
    	phy-reset-post-delay = <10>;
    
    Is it preferred to change the device-tree here or should I keep the reset
    from board_init() like I have it now?  If I should use the dt, is there
    a similar way for dealing with VIO?
