boot/uboot: add option to pass custom variables to U-Boot build
U-Boot supports a number of environment variables to pass specific
information. The following patches were submitted in the past to one
some specific Config.in option to pass some of these variables:
- http://patchwork.ozlabs.org/patch/881197/ proposed an option to
pass a custom EXT_DTB= variable
- http://patchwork.ozlabs.org/patch/1018245/ proposed an option to
pass a custom DEVICE_TREE= variable
Instead of adding one Config.in option for each of those variables,
let's provide a generic mechanism to pass arbitrary variables during
U-Boot build step.
