Since commit f60658c6ae "xen/arm: Stop relocating Xen", the position of Xen in memory is not printed anymore. This can make difficult to debug early code. As Xen is not relocated anymore, we can add Xen as boot module before calling boot_fdt_info(). With that, the function will print Xen module information along with all the other modules.
