arm: link a device tree blob into the xen image
Link a device tree blob (DTB) into the xen image. This is loaded
immediately after Xen and xen_start() is called with the correct
address in atag_paddr.
The DTB file must be supplied by setting the CONFIG_DTB_FILE variable
in .config or on the make command line.
