[Buildroot] [PATCH 2/3] board/lego/ev3: fix max U-Boot flash size

[David Lechner <david@lechnology.com>]

The first stage bootloader on LEGO MINDSTORMS EV3 only loads the first
256K of the flash memory (this is hard-coded in an EEPROM). So, the
second stage bootloader (U-Boot) cannot exceed this size.
