Currently some devices (in this case kbd, fb, vesa) are initialised after
CPU/firmware setup. On some platforms (e.g. PPC) kvm__arch_setup_firmware() may
be making a device tree. Any devices added after this point will be missed!
Tiny refactor of builtin-run.c, moving timer start, firmware setup, cpu init
to occur last.
