[U-Boot] [PATCH 3/5] tools: use files from scripts/dtc/libfdt where possible

Prior to this commit, tools/Makefile pulls all libfdt files from
lib/libfdt.
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
This commit changes them to #include ones from scripts/dtc/libfdt.
Unfortunately, U-Boot locally modified the following 3 files:
fdt_ro.c fdt_wip.c fdt_rw.c
I did not touch them in order to avoid unpredictable impact.
The fdt_region.c is U-Boot own file. This is also borrowed from
lib/libfdt/.
