kconfig: update to Linux 5.3-rc3 ...

Recently, Linux merged some important fixes.

Commit 8e2442a5f86e ("kconfig: fix missing choice values in auto.conf")
Commit 0c5b6c28ed68 ("kconfig: Clear "written" flag to avoid data loss")

Barebox must import them.

IMX: do_hab calls strcat on uninitialised memory

scripts: imx: support signing for i.MX8MQ ...

Implement signing of the PBL for i.MX8MQ.
The imagesize is also modified to i.MX8MQ to only contain the PBL.
This obsoletes the max_load_size, which is kept for other boards
currently using it.

kconfig: update to Linux 5.2-rc4 ...

The previous sync was Linux 4.20. This updates Kconfig to Linux 5.2-rc4.

I adjusted the top Makefile as well because Linux commit 058507195b53
("kbuild: move ".config not found!" message from Kconfig to Makefile")
moved the .config check from Kconfig to Makefile.

I also made auto.conf a mandatory include file, and remove it from the
prerequisites of other targets. We are safe because Make is immediately
terminated when syncconfig fails to generate auto.conf.

Highlights:

 - The parser has no more shift/reduce conflicts

 - The lexer was rewritten more simply

 - The token lookup table was deleted

 - Replace license boilerplates with SPDX

 - Compile C files as separate units

 - Do not overwrite .config when the content was not changed

 - Lots of bug-fixes and cleanups

kbuild: do not drop -I without parameter ...

Linux commit 48f6e3c
[ Adjusted for barebox for some missing commits ]

The comment line for addtree says "skip if -I has no parameter".

What it actually does is "drop if -I has no parameter".  For example,
if you have the compiler flag '-I foo' (a space between), it will be
converted to 'foo'.  This completely changes the meaning.

What we want is, "do nothing" for -I without parameter so that
'-I foo' is kept as-is.

images/mvebu: Convert Armada machines to mvebuimg ...

The results are bytewise identical apart from armada-xp-db where the
(AFAIK unused) parameters for the binary header are different (i.e.
0000005b 00000000 instead of 0000005b 00000068 for all other boards).

The advantage is that the build system now knows about the binary
headers and changes to them result in a rebuild of the images.

mvebuimg: new tool to create kwb version1 boot images ...

The purpose is the same as kwbimage, but the code is saner (in my eyes
at least). Currently it only supports creating v1 images, but can be
easily expanded to support v0 and extraction, too. The main advantage is
that the file name of the binary headers is passed via cmdline and so
the barebox build system can know about them without specifying them
twice.

Additionally it supports more than one binary header and doesn't create
broken images when running on a big endian platform.

scripts: kwbimage: fix build with non-glibc systems ...

get_current_dir_name is a glibc extension, thus replace it
with a call to standard POSIX pathconf/malloc/gecwd.

The result slightly differs, because get_current_dir_name consults
the $PWD environment variable as as well, but that's ok, as it's
just an error message.
