This adapts all files that were identifed by licensecheck
(https://salsa.debian.org/build-common-team/licensecheck.git) as
licensed under the GPL.

The advantage is that these specifiers are machine-parseable which helps
license conformance, e.g. for packaging barebox in Debian.

While touching these files also do some minor comment reformatting to
get some uniform layout.

When we are linked at 0x0 and running at 0x01000000 then
get_runtime_offset() should return 0x01000000 and not 0xff000000. This
makes get_runtime_offset() more consistent and better understandable.

This was tested on a Freescale i.MX53 Quickstart board. Additionally
relocate_to_adr() was tested since that is normally not called.

Status quo is that initially a size of 64 MiB is assumed (which is also
used to determine the size of the malloc area) and then later the dtb
is fixed up with the actually available RAM which is then used.

Instead detect the real RAM size earlier and don't fixup the device tree.
The device tree is fixed up instead by generic code. This way the malloc
area is more appropriately sized and RAM detection is more similar to mach-imx
which is both nice.

This file originates in Linux.  Linux has it under include/linux/
directory since commit dccd2304cc90.
Let's move it to the same place as well in barebox.

This commit was generated by the following commands:

  find -name '*.[chS]' | xargs sed -i -e 's:<sizes.h>:<linux/sizes.h>:'
  git mv include/sizes.h include/linux/

This converts Marvell Armada XP based PlatHome Openblocks AX3-4
to PBL_MULTI_IMAGES. A DT overlay is added to keep possible
barebox-specific changes separated and added to lowlevel
board init.
