zedboard: Patch default U-Boot environment for zedboard
This patch changes the U-Boot's default environment to boot Zedboard out-of-the-box from SD card. The sdboot procedure tries to load a file system.bit into the Zynq's PL (only if it exists). It is also possible to alter the booting by an uEnv.txt file located on your SD card. The uEnv.txt is a plain text file with <key>=<value> pairs one per line.
