- Revert the commit c0e032e0090d65 ("scripts/dtc: Update to upstream
- version v1.4.3")
- libreCMC uses the dtc from the kernel also in u-boot, but when we compile
- against kernel 4.9 we run into some errors because it is too old now.
- Add the options only when they are supported to make it compatible with
- dtc from kernel 4.9.
