[Buildroot] [PATCH] zedboard: uboot: load env earlier

[Gwenhael Goavec-Merou]

From: Gwenhael Goavec-Merou <gwenhael.goavec-merou at trabucayre.com>

By default, with the original patch bootcmd runs sdboot before loading uEnv.txt.
Consequently, if the user change modeboot, the user's defined content is updated
too late.
By loading uEnv.txt before 'run $modeboot' the correct boot mode is used instead
of default mode.
