wandboard: Use U-Boot 2016.07

Upgrade U-Boot version to 2016.07 and make proper use of U-Boot
distro configuration features.

Provide a boot.scr binary script that is one of the standard ways to
pass a U-Boot script with distro features enabled.

With this method the uboot-env.txt file is no longer needed, so it is
removed.
