x86: devicetree: Add missing early_init_dt_setup_initrd_arch stub
commit 977cb76d52e7aa040e18a84b29fe6fd80d79319b upstream.
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.
