MLK-13645 mx7ulp: Modify FDT file to disable SD3.0 for mfgtool

Since the SD3.0 kernel driver needs M4 image support, this causes problem to mfgtool.
To decouple the relationship, we modify the FDT file in u-boot to disable
SD3.0 when booting from USB for mfgtool. So the kernel won't depend on M4 image.
