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.

Most callers of arm_setup_stack substract a fixed offset of 8, 12 or 16
bytes from the stack top. This is unnecessary as on ARM we have a stack
that decrements before storing values. Substracting this offset probably
goes back to the U-Boot version we forked from. Stop this now.

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.

The imx53 SOC features 128kB of internal SRAM which is commonly used in
early stages of barebox to store the stack. Avoid magic numbers while
addressing this RAM.
