The script iterates over the given devicetrees and creates both
fdt_x node as well as a conf-node for each passed dt.

But there is a slight bug in that it always references fdt_1 in each
conf node instead of the matching fdt_x as expected.

So fix that by referencing the number of the current dt similar to
how the fdt_x nodes gets created.

On a distribution with no python2 installed and no
python->python3 symlink the script will fail to execute.
Specify python3 explicitly as it's already a requirement

A trusted execution environment should also get loaded as loadable from
a fit image, so add the possibility to present a tee.elf to make_fit_atf.py
that then gets included as additional loadable into the generated its.

For ease of integration the additional loadable is created as atf_(x+1)
after all others to re-use core generation loops.

Tested against the combinations of 1-part-atf and multi-part-atf each
time with and without a tee binary present.

The commit 619f002d ("rockchip: make_fit_atf.py: fix loadables property
set error") fixed the double-loading of the primary atf-image, but didn't
take into account that there may be rare atf images with only that main
section present.

Right now this will result in a broken its due to the loadables section not
getting closed correctly, so fix that by adapting the guards around the loop.

The guards now protect against 0 segments when the bl31 binary doesn't
contain any section and 1 segment when only a core atf section is present.

make_fit_aft.py depends on the non-standard library pyelftools to pull
out PT_LOAD segments from ELF files. However, this is as easy to do
manually, without imposing the extra dependency on users.

Structures in the ELF file are unpacked into variables named to exactly
match the ELF spec to ensure the destructuring code is reasonably
self-documenting.

Right now rockchip platform need to copy bl31.elf into u-boot
source directory to make use of building u-boot.itb.

So, add environment variable BL31 like Allwinner SoC so-that the
bl31.elf would available via BL31.

If the builds are not exporting BL31 env, the make_fit_atf.py
explicitly create dummy bl31.elf in u-boot root directory to
satisfy travis builds and it will show the warning on console as

 WARNING: BL31 file bl31.elf NOT found, resulting binary is non-functional
 WARNING: Please read Building section in doc/README.rockchip

Note, that the dummy bl31 files were created during not exporting
BL31 case would be removed via clean target in Makefile.

This patch cleans up make_fit_atf.py in the following way:

* Fix all issues reported by pylint
* Move copyright notice from file-to-generate to script
* Fix of-by-one bugs in loadables property
* Remove commented-out (dead) code.

Besides the bugfix no intended changes.

Tested on RK3399-Q7 with TF-A v2.1 as BL31.

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 a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.
