fdt: ARM: Add fdtcontroladdr to set device tree address in environment
This adds support for a new environment variable called 'fdtcontroladdr'. If defined, the hex address is used as the address of the control fdt for U-Boot. Note: I have not changed CONFIG_PRAM section as I already have an outstanding patch on that. Signed-off-by: Simon Glass <sjg@chromium.org>
