[PATCH v2 3/3] libfdt: split fdt_region declarations out to <fdt_region.h>

[sjg at google.com]

fdt_region APIs are not part of libfdt. They are U-Boot extension
for the verified boot. Split the declarations related to fdt_region
out of <fdt_region.h>. This allows <linux/libfdt.h> to become a
simple wrapper file, like Linux does.

I am resending this after two years since v1.

My previous attempt sank by this comment:

Two years have passed, but I still do not see such code
in upstream DTC.


Changes in v2:
  - Rebase

Applied to u-boot-dm, thanks!
