  From: Simon Glass <simon.glass@canonical.com>

Add a demo-rom binman entry that reuses the rom_common template and
packages the demo example binary alongside the device tree and fdtmap,
producing a demo.rom that can be run on qemu-x86.

Enable CONFIG_EXAMPLES in qemu-x86_defconfig so the demo is built by
default.
