uboot-sunxi: fix build by adding comparabilities for old dtc
We use the dtc from the kernel and that does not have all the options which u-boot would like to use now. make these parameters optional.

+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.
