uboot-sunxi: fix build by adding comparabilities for old dtc

Browse source 
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.
