You need to start the FEC clock here too, otherwise ethernet won't work. Same 
thing as on mx28evk. And I noticed that on other platforms too, so maybe that 
should be somehow the other way around -- turn on the ethernet clock by default.

The rest seems OK. I'll update the .dts file once we get the rest of the stuff 
in (SPI and i2c).

btw. is someone converting the mxs-lcd ?
