images: pbl: verify CONFIG_BAREBOX_MAX_IMAGE_SIZE is not exceeded ...

For platforms such as the at91, the boot ROM imposes an upper limit
on barebox file size.  Prior to 5a1a5ed253 ("ARM: images: use piggydata"),
BAREBOX_MAX_PBLX_SIZE seems to have been the way to go for limiting
the size of the final barebox binary when using the PBL.
With pblx removed, this variable is of no use, so have the existing
BAREBOX_MAX_IMAGE_SIZE replace its functionality.

Currently BAREBOX_MAX_IMAGE_SIZE is only checked against in the non-PBL
case, so add a check in the PBL case as well.

LICENSES: adopt Linux-like LICENSES directory structure ...

At the moment
  grep -r --exclude-dir=.git 'SPDX-License-Identifier:' | \
    grep -v 'GPL-2.0'

shows me 39 non-dually-licensed source code files (SoCFPGA) that have a
BSD-3-Clause license _identifier_.
There seems to be no barebox BSD-3-Clause license  _text_ however,
which runs afoul of the first clause of the license.

To account for this and future contributions which are licensed under
non-GPL-2.0-but-compatible licenses, create a new LICENSES directory
like the one Linux has, where licenses are located.

This also removes the jumptable exception inherited from U-Boot:

The LICENSES/exceptions directory is therefore empty as well as
the LICENSES/other directory, which might house new licenses in future.
They are added along this commit however, because upstream
checkpatch.pl introduced with a later commit depends on their
existence.

defaultenv: Fix dependencies ...

The defaultenv should be rebuilt once a file in it has changed.
the genenv script always generates the environment file to a temporary
file. Only if it has changed to the last target file the temporary file
is moved over the target file. This means we always have to call genenv,
thus replace "if_changed" with "cmd".
With this dependencies are correctly tracked. New or changed files
result in new image builds whereas unchanged environments do not
unnecessarily result in new images.
