scripts/dtc: reinstate building of fdtget along with dtc ...

Unlike Linux, barebox has a build-time dependency on the fdtget utility.
For this reason, we can't import the kernel dtc Makefile by mere
copying. Reinstate the fdtget-specific bits that got lost in the
last dtc update. This fixes barebox imd generation which has caused
following error message in master:

This commit was generated by running ./scripts/dtc/update-dtc-source.sh
from the otherwise empty directory.

Besides updating to the most recent dtc release (so that /omit-if-no-ref/
becomes available), it reinstates the dtc-lexer.l and
dtc-parser.y files which were erroneously deleted in place of their
pregenerated _shipped.c versions.

Also removed are fdtputc.c and fdtdump.c, which aren't built or used
anywhere.

scripts/dtc: fix update-dtc-source.sh for barebox use ...

Unlike Linux:
- barebox' scripts/gen-dtb-s has a dependency on fdget,
  thus change the script to copy fdget.c as part of the update.
- has the libfdt source files in the same directory as the rest
- we don't have/need Makefile.libfdt

Adjust the update-dtc-source.sh script to account for this, so
it can be used to update the scripts/dtc directory. To do so, run

kbuild: generate lexer and parser during build instead of shipping ...

Recent kernel versions run flex and bison to generate lexers and
parsers from real source files such as *.l and *.y . This provides
better maintainability than version-controlling pre-generated C files
with a "_shipped" suffix.

This commit imports flex and bison rules from Linux, and deletes
pre-generated parsers and lexers.

Refer to the following commits in Linux:

 - 033dba2ec06c ("kbuild: prepare to remove C files pre-generated by
   flex and bison")

 - 29c833061c1d ("kconfig: generate lexer and parser during build
   instead of shipping")

kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level Makefile ...

Linux commit 9a8dfb3

Files suffixed by .lex.c, .tab.[ch] are generated lexers, parsers,
respectively.  Clean them up globally from the top Makefile.

Some of the final host programs those lexer/parser are linked into
are necessary for building external modules, but the intermediates
are unneeded.  They can be cleaned away by 'make clean' instead of
'make mrproper'.

Apparently our dtc code comes from the Kernel which doesn't have the
upstream version of fdtget.c and it doesn't compile. This patch
changes fdtget.c to the upstream version as of 1.4.6. This isn't
noticed in the Kernel because fdtget isn't compiled there.
