grub2: fix initrd size restriction bug
The current grub2 fails on loading large initrd file (> 500M) since the initrd size is added to the addr_min and causes the failure. Fix it by picking a patch from grub2 upstream. Signed-off-by: Shan Hai <shan.hai@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
