ARM: Compile dtbs for lowlevel code ...

When no PBL is used then the DTB is used in the real barebox binary. We
already have lwl-y for code which needs to be in PBL when existing and
in the real barebox binary otherwise. Do the same for the DTBs and
compile them with lwl-dtb-y.

scripts/dtc: mention dtc project in update-dtc-source.sh commit message ...

update-dtc-source.sh generates the commit message after it runs
to completion. The word upstream is often used to refer to the
Linux kernel within barebox, so change the wording to refer
explicitly to dtc upstream.

To avoid keeping stale files in the scripts/dtc directory, care had to
be taken to delete all files except for the ones native to barebox.
Make this less error-prone by having careupdate-dtc-source.sh delete
these files as part of the update process.

scripts/dtc: reinstate building of fdtget along with dtc ...

Unlike Linux, barebox has a build-time dependency on the fdtget utility.
For this reason, we can't import the kernel dtc Makefile by mere
copying. Reinstate the fdtget-specific bits that got lost in the
last dtc update. This fixes barebox imd generation which has caused
following error message in master:

	gen-dtb-s: line 37: scripts/dtc/fdtget: No such file or directory

scripts/dtc: Reinstate barebox-specifics in update-dtc-source.sh ...

The barebox update-dtc-source.sh differs from the Linux one in that it
installs fdtget as well, because it's required for barebox IMD to work.
Readd fdtget.c to DTC_SOURCE and while at it reinstate the old comments.

dtc: optionally add add __symbols__ to build-in devicetree ...

The devicetree overlay driver requires the __symbols__ node to resolve
phandles to the base devicetree. If Barebox has to apply the overlay to
the live devicetree, the build-in devicetree must be built with the
__symbols__ node.

It is configurable, because adding __symbols__ significantly increases
the size of the devicetree binary. When configuring Barebox, a developer
should be able to enable or disable devicetree overlay support and as
this only affects the build-in devicetree, which is linked to the image
anyway, use a Kconfig item for configuring the __symbols__.

common: add generic CONFIG_UBSAN plumbing ...

-fsanitize=undefined allows compile-time instrumentation of code to detect
some classes of runtime undefined behavior.

In preparation for allowing arches to provide infrastructure in support
of this feature, add some generic UBSAN options and associated plumbing.

These are only shown in the debug menu when the arch selects the
appropriate symbol. The option is named equally to their Linux counterparts.

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.
