cover LEGO MINDSTORMS EV3 updates

Here are a few more updates for LEGO MINDSTORMS EV3 based on feedback from my recent patch to use the mainline kernel [1].

I have boot-tested both the flash image and the SD card image.

PATCH 2/3 lego: ev3: Use genimage to rename uImage file

In reply to David Lechner

This uses a genimage feature to rename the uImage file instead of manually creating a symlink in the post-image script.
