$(always) is added to targets by scripts/Makefile.build.
Moreover, filechk does not need .*.cmd files.
Adding these two files to targets is redundant.

Use filechk to generate asm-offsets.h and generic-asm-offsets.h.
Based on a patch by Valdis Kletnieks.

The rules "cmd_generic-offsets" and "cmd_offsets" are almost the
same. (The difference is only the include guards.)
They can be merged.
This commit is mostly inspired by the following commit of Linux.

KBuild abuses the asm statement to write to a file and
clang chokes about these invalid asm statements. Hack it
even more by fooling this is actual valid asm code.

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in
arch/{arm,nds32}/lib/asm-offsets.c.

Generate include/generated/generic-asm-offsets.h and
include/generated/asm-offsets.h in ./Kbuild.
This commit also changes the include guard.
Before this commit, __ASM_OFFSETS_H__ was used for both of them.
So we could not include generic-asm-offsets.h and asm-offsets.h
at the same time.
This commit renames the include guard of the former to
__GENERIC_ASM_OFFSETS_H__.
