[U-Boot] MMC is broken on mx28evk

[Lauri Hintsala]

Hi Marek,

I built U-Boot 2012.04-rc1 and tried it with mx28evk. MMC seems to be 
broken. Reverting your commit 3687c4 (i.MX28: Do data transfers via DMA 
in MMC driver) fix the issue.

Also there is issue in setting MAC address. Console logs are at the end 
of this mail.

Best regards,
Lauri Hintsala
