[U-Boot] [PATCH] integrator: pass a Device Tree by default

[Linus Walleij]

This, enabled the FDT library for the Integrators, updates
the Integrator/CP default command to load and pass a Device
Tree when booting the kernel from the on-board ethernet,
define same environment for the Integrator/AP and move the
load address around to something even.
