Add support for these functions in the Python binding. This patch stands
in for a pending upstream change.

This currently fails to reduce the device-tree bytearray size. Fix this.
This stands in for a pending upstream change.

This provides various patches sent to the devicetree-compiler mailing list
to enhance the Python bindings. A final version of this patch may be
created once upstreaming is complete, but if it takes too long, this can
act as a placeholder.
New pylibfdt features:
- Support for most remaining, relevant libfdt functions
- Support for sequential-write functions
Changes are applied to existing U-Boot tools as needed.

Add missing CC and LDSHARED variables to the Makefile to pass the
correct C compiler and linker path to the build of _libfdt.so .

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are
allowed so when they were used before we continue to use them.

All of these host tools are apparently written for Python2,
not Python3.
Use 'python2' in the shebang line according to PEP 394
(https://www.python.org/dev/peps/pep-0394/).

The pylibfdt is used by dtoc (and, indirectly by binman), but there
is no reason why it must be generated in the tools/ directory.
Recently, U-Boot switched over to the bundled DTC, and the directory
structure under scripts/dtc/ now mirrors the upstream DTC project.
So, scripts/dtc/pylibfdt is the best location.
I also rewrote the Makefile in a cleaner Kbuild style.
The scripts from the upstream have been moved as follows:
lib/libfdt/pylibfdt/setup.py -> scripts/dtc/pylibfdt/setup.py
lib/libfdt/pylibfdt/libfdt.i -> scripts/dtc/pylibfdt/libfdt.i_shipped
The .i_shipped is coped to .i during building because the .i must be
located in the objtree when we build it out of tree.
