My goal is to sync lib/libfdt/ with scripts/dtc/libfdt/, that is,
make lib/libfdt/ contain only wrapper files.

fdt_region.c was written only for U-Boot to implement the verified
boot.  So, this belongs to the same group as common/fdt_support.c,
which is a collection of U-Boot own fdt helpers.

Move lib/libfdt/fdt_region.c to common/fdt_region.c .  This is
necessary only when CONFIG_(SPL_)_FIT_SIGNATURE is enabled.

Actually it was written for the fdtgrep tool as well, which was sent
upstream, but not accepted.

Perhaps I should try to send that again.
