Remove including timestamp.h in version.h

Header file version.h does not use anything from timestamp.h. Including of
timestamp.h has side effect which cause recompiling object file at every
make run because timestamp.h changes at every run.

So remove timestamp.h from version.h and include timestamp.h in files
which needs it.

This change reduce recompilation time of final U-Boot binary when U-Boot
source files were not changed as less source files needs to be recompiled.

This patch moves version_string[] from version.h to version_string.h and

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.

Add GIT version information (commid ID) to untagged U-Boot versions

As done in the linux kernel, the U-Boot version (U_BOOT_VERSION)
of all unreleased (untagged) U-Boot images will be automatically
extended upon compiletime with a part of the GIT commit ID and
possibly with "dirty" if uncommited changes are detected.

Here an example for the resulting version:
"U-Boot 1.1.4-g3457ac18-dirty"

The version is now maintained in the toplevel Makefile and the
version headers are autogenerated.

Patch by Yuli Barcohen, 7 Aug 2003:

According to the MPC8260 User's Manual, PCI_MODE signal should be

include/version.h: workaround sysroot inc order

On some systems the host system or even the cross sysroot can
contain a version.h. This leads to the wrong file being picked
up and a PLAIN_VERSION undefined error.

This workaround symlinks the version.h into the tool folder to
allow reordering of search folders.
