This adds support to the LAN9212 chip included in the board and extend
the environment to easy netboot use.

Changes in v2:
- Move GPIO initialization to board_early_init_f;
- Extend commitlog;

My schematics says it is a LAN9512.

You would better use #ifdef	CONFIG_CMD_USB instead, like we do on mx28evk.

This would make things easier for someone that wants to test the board
without USB support, by just undefing CONFIG_CMD_USB, which in turn
remove all USB related support.

Right; a typo!
