package/boot/uboot-sunxi/patches/220-compatible-old-dtc.patch

-Revert the commit c0e032e0090d65 ("scripts/dtc: Update to upstream 
-version v1.4.3")
-OpenWrt 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.
