lego-ev3: Add support for LEGO Mindstorms EV3 (AM1808)

Thanks for the feedback! Updated patch below. Changes:
 - Change SERIAL_CONSOLE to new SERIAL_CONSOLES format.
 - Move SPL_BINARY variable into lego-ev3 machine config
 - Check for KERNEL_DEVICETREE_BUNDLE before uImage manipulation.
 - Fix line wrapping errors introduced by MUA
