Add SPDX license identifiers to all Make/Kconfig files which:
- Have no license information of any form
These files fall under the project license, GPL v2 only. The resulting SPDX
license identifier is:
GPL-2.0-only

I fixed a similar build error in commit 1b1e4ee86e00 ("sh: fix build
error for empty CONFIG_BUILTIN_DTB_SOURCE"), but it came back again.
Since commit 37c8a5fafa3b ("kbuild: consolidate Devicetree dtb
build rules"), the combination of CONFIG_OF_EARLY_FLATTREE=y and
CONFIG_USE_BUILTIN_DTB=n results in the following build error:
make[1]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o',
needed by 'arch/sh/boot/dts/built-in.a'. Stop.
Prior to that commit, there was only one path to descend into
arch/sh/boot/dts/, and arch/sh/Makefile correctly guards it with
CONFIG_USE_BUILTIN_DTB:
core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/
Now, there is another path to descend there from the top Makefile
when CONFIG_OF_EARLY_FLATTREE=y. If CONFIG_USE_BUILTIN_DTB is disabled,
CONFIG_BUILTIN_DTB_SOURCE is invisible instead of defined as "".
Add obj-$(CONFIG_USE_BUILTIN_DTB) guard to avoid the attempt to build
the non-existing file.

If CONFIG_USE_BUILTIN_DTB is enabled, but CONFIG_BUILTIN_DTB_SOURCE
is empty (for example, allmodconfig), it fails to build, like this:
make[2]: *** No rule to make target 'arch/sh/boot/dts/.dtb.o',
needed by 'arch/sh/boot/dts/built-in.o'. Stop.
Surround obj-y with ifneq ... endif.
I replaced $(CONFIG_USE_BUILTIN_DTB) with 'y' since this is always
the case from the following code from arch/sh/Makefile:
core-$(CONFIG_USE_BUILTIN_DTB) += arch/sh/boot/dts/

We need to add "clean-files" in Makfiles to clean up DT blobs, but we
often miss to do so.
Since there are no source files that end with .dtb or .dtb.S, so we
can clean-up those files from the top-level Makefile.
