Use the same reboot approach on i386 coreboot and qemu as we do on
        BIOS.

        * conf/i386-coreboot.rmk (kernel_img_HEADERS): Add `cpu/reboot.h'.
        (reboot_mod_SOURCES): Remove `kern/i386/reboot.c'.
        * kern/i386/reboot.c: Remove.
        * include/grub/i386/reboot.h (grub_reboot): Export function.
        * kern/i386/pc/startup.S (grub_reboot): Move from here ...
        * kern/i386/realmode.S (grub_reboot): ... to here.  Jump to
        0xf000:0xfff0 instead of 0xffff:0x0000.
        [!GRUB_MACHINE_PCBIOS] (prot_to_real): Do not restore interrupts.
        * kern/i386/qemu/startup.S: Include `"../realmode.S"'.
