fdt: ARM: Add device tree control of U-Boot (CONFIG_OF_CONTROL)
This adds a device tree pointer to the global data. It can be set by board code. A later commit will add support for making a device tree binary blob available to U-Boot for run-time configuration. Signed-off-by: Simon Glass <sjg@chromium.org>
