Documentation/x86/boot: Peserve type_of_loader=13 for barebox

barebox[1], a bootloader for mostly ARM and MIPS embedded systems, can
also be built as EFI payload for x86[2] to provide redundant power-fail
safe, watchdog-supervised boot up.

Since its v2015.09.0 release, it has been booting Linux on x86 with
type_of_loader=0xff[3]. Reserve 13, the next free id, so that can be
used instead in the future.
