SPDX: Convert all of our single license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one.

Move timestamp and version files into 'generated' subdir There is a rather subtle build problem where the build time stamp is not updated for out-of-tree builds if there exists an in-tree build which has a valid timestamp file. So if you do an in-tree build, then an out-of-tree build your timestamp will not change. The correct timestamp_autogenerated.h lives in the object tree, but it is not always found there. The source still lives in the source tree and when compiling version.h, it includes timestamp_autogenerated.h. Since the current directory is always searched first, this will come from the source tree rather than the object tree if it exists there. This affects dependency generation also, which means that common/cmd_version.o will not even be rebuilt if you have ever done an in-tree build. A similar problem exists with the version file. This change moves both files into the 'generated' subdir, which is already used for asm-offsets.h. Then timestamp.h and version.h are updated to include the files from there. There are other places where these generated files are included, but I cannot see why these don't just use the timestamp.h and version.h headers. So this change also tidies that up. I have tested this with in- and out-of-tree builds, but not SPL. I have looked at various other options for fixing this, including sed on the dep files, -I- and -include flags to gcc, but I don't think they can be made to work. Comments welcome.
