lib: libfdt: wrap scripts/dtc/libfdt/* where possible
lib/libfdt/ and scripts/dtc/libfdt have the same copies for the
followings 6 files:
fdt.c fdt_addresses.c fdt_empty_tree.c fdt_overlay.c fdt_strerr.c
fdt_sw.c
Make them a wrapper of scripts/dtc/libfdt/*. This is exactly what
Linux does to sync libfdt. In order to make is possible, import
<linux/libfdt.h> and <linux/libfdt_env.h> from Linux 4.14-rc5.
Unfortunately, U-Boot locally modified the following 3 files:
fdt_ro.c fdt_wip.c fdt_rw.c
The fdt_region.c is U-Boot own file.
I did not touch them in order to avoid unpredictable impact.
