kbuild: Really don't clean bounds.h and asm-offsets.h
Commit 7d3cc8b tried to keep bounds.h and asm-offsets.h during make clean by filtering these out of $(clean-files), but they are listed in $(targets) and $(always) and thus removed automatically. Introduce a new $(no-clean-files) variable to really skip such files in Makefile.clean. Signed-off-by: Michal Marek <email@example.com>

Kbuild will assume the directories to be in the same relative path as the
Makefile if no absolute path is specified (path does not start with '/').
+To exclude certain files from make clean, use the $(no-clean-files) variable.
+This is only a special case used in the top level Kbuild file:
+ no-clean-files := $(bounds-file) $(offsets-file)
Usually kbuild descends down in subdirectories due to "obj-* := dir/",
but in the architecture makefiles where the kbuild infrastructure
is not sufficient this sometimes needs to be explicit.
