fdt: Tell the FDT library where the device tree is
This change adds a call to set_working_fdt_addr near the end of u-boot initialization which tells the fdt command/library where the device tree is. This makes it possible to use the fdt command to look at the active device tree since otherwise there would be no way to know what address it was at to set things up manually.
