Use newly-added Multiboot support in coreboot.

        * conf/i386-coreboot.rmk (kernel_elf_SOURCES): Replace
        `kern/i386/coreboot/mmap.c' with `kern/i386/multiboot_mmap.c'.

        * kern/i386/coreboot/startup.S: Enable Multiboot header, fix its
        alignment, set `MULTIBOOT_MEMORY_INFO' flag.
        (codestart): Store the MBI in `startup_multiboot_info' when we're
        being loaded using Multiboot.

        * kern/i386/coreboot/init.c (grub_machine_init): Move
        grub_at_keyboard_init() call to beginning of function (useful for
        debugging).  Call grub_machine_mmap_init() before attempting to use
        grub_machine_mmap_iterate().
        (grub_lower_mem, grub_upper_mem): Move from here ...
        * kern/i386/multiboot_mmap.c (grub_lower_mem, grub_upper_mem): ... to
        here (new file).

        * include/grub/i386/coreboot/memory.h (grub_machine_mmap_init): New
        function prototype.
