sandbox: Build a device tree file for sandbox
Add support for building a device tree for sandbox's CONFIG_OF_HOSTFILE option to make it easier to use device tree with sandbox. This adjusts the Makefile to build a u-boot.dtb file which can be passed to sandbox U-Boot with: ./u-boot -d u-boot.dtb Signed-off-by: Simon Glass <sjg@chromium.org>
