imx6sabresd: boot to /init in mfgtools mode
Buildroot supplies a nice /init wrapper script to use when booting from a
ramdisk.
We add a patch to u-boot to tell the kernel to boot into /init (instead of
/linuxrc) on i.MX6, when booting in mfgtools mode. This way we can boot a
buildroot system entirely through USB.
