The original UBOOT_FIXUP_LIBFDT_INCLUDE hook only works for u-boot versions
starting from v2017.11.
As older u-boot versions are still in common use today, e.g. in the
ci20_defconfig, extend the hook to cover a wider range of u-boot versions.
The main code change was proposed by Arnout Vandecappelle in [1].
Testing and comment changes were done by Thomas De Schampheleire.
Additional (build) testing done by Yann.

This was tested with the following defconfigs, that each excercise one
case:
