of this. The copyright text cannot be added to the .ttf files, so put it

These is a growing trend to license DT files dual GPL and X11
especially in the Linux community. It allows easier reuse of
device trees for other software projects.
This commit prepares for doing so in U-Boot too, since DT files are
often copied from the kernel to U-Boot.

In [1] we discussed how we should deal with dual (or, more generally,
multiple) licensed files. Add this to Licenses/README so it's
properly documented.

The SPDX License List version 1.19 now contains an official entry for
the IBM-pibs license. However, instead of our suggestion "ibm-pibs",
the SPDX License List uses "IBM-pibs", with the following rationale:
"The reason being that all other SPDX License List short identifiers
tend towards using capital letters unless spelling a word. I'd prefer
to be consistent to this end".
Change the license IDs to use the official name.

This commit adapts the files that were derived from PIBS (PowerPC
Initialization and Boot Software) codeto using SPDX License
Identifiers.
So far, SPDX has not assigned an official License ID for the PIBS
license yet, so this should be considered preliminary.
Note that the following files contained incorrect license information:
arch/powerpc/cpu/ppc4xx/4xx_uart.c
arch/powerpc/cpu/ppc4xx/start.S
arch/powerpc/include/asm/ppc440.h
These files included, in addition to the GPL-2.0 / ibm-pibs dual
license as inherited from PIBS, a GPL-2.0+ license header which was
obviously incorrect. This has been removed.

Like many other projects, U-Boot has a tradition of including big
blocks of License headers in all files. This not only blows up the
source code with mostly redundant information, but also makes it very
difficult to generate License Clearing Reports. An additional problem
is that even the same lincenses are referred to by a number of
slightly varying text blocks (full, abbreviated, different
indentation, line wrapping and/or white space, with obsolete address
information, ...) which makes automatic processing a nightmare.
To make this easier, such license headers in the source files will be
replaced with a single line reference to Unique Lincense Identifiers
as defined by the Linux Foundation's SPDX project [1]. For example,
in a source file the full "GPL v2.0 or later" header text will be
replaced by a single line:
SPDX-License-Identifier: GPL-2.0+
We use the SPDX Unique Lincense Identifiers here; these are available
at [2].
Note: From the legal point of view, this patch is supposed to be only
a change to the textual representation of the license information,
but in no way any change to the actual license terms. With this patch
applied, all files will still be licensed under the same terms they
were before.
Note 2: The apparent difference between the old "COPYING" and the new
"Licenses/gpl-2.0.txt" only results from switching to the upstream
version of the license which is differently formatted; there are not
any actual changes to the content.
Note 3: There are some recurring questions about linense issues, such
as:
- Is a "All Rights Reserved" clause a problem in GPL code?
- Are files without any license header a problem?
- Do we need license headers at all?
The following excerpt from an e-mail by Daniel B. Ravicher should help
with these:

| It is not a conflict to grant a license and also reserve all rights, as
| implicit in that language is that you are reserving all "other" rights
| not granted in the license. Thus, a file with "Licensed under GPL, All
| Rights Reserved" would mean that it is licensed under the GPL, but no
| other rights are given to copy, modify or redistribute it.
