[Buildroot] [PATCH 14/14] board/boundarydevices: update u-boot script for 3.14 kernels

[Gary Bisson <gary.bisson@boundarydevices.com>]

This script will support coming platforms such as iMX6SoloX or
iMX6QuadPlus.

One important change is that the script now relies on U-Boot to make the
display detection in order to simplify the script.
