x86: devicetree: Add missing early_init_dt_setup_initrd_arch stub
This patch fixes the following build failure: drivers/built-in.o: In function `early_init_dt_check_for_initrd': /home/florian/dev/kernel/x86/linux-2.6-x86/drivers/of/fdt.c:571: undefined reference to `early_init_dt_setup_initrd_arch' make: *** [.tmp_vmlinux1] Error 1 which happens as soon as we enable initrd support on a x86 devicetree platform such as Intel CE4100.
