4253eae005 boards: nrf52840_pca10056: Rename board to nrf52840dk_nrf52840
The nRF52840 DK board target, so far known as nrf52840_pca10056,
is renamed to nrf52840dk_nrf52840.
Its documentation and all references to its name in the tree are
updated accordingly. Overlay and configuration files specific to
this board are also renamed, to match the new board name.

This is joint work with Kumar Gala (see signed-off-by).

fe6107f2b3 doc: finish reworking the board porting guide
Now that the west parts of this file are in better shape, it seems a
shame not to flesh out the rest a bit more.

It's been a while since we looked at this document, as it's still
referring to boards (like Arduino 101) that are no longer supported by
Zephyr, and is generally lacking in concrete, step-by-step advice
for going from zero to working board.

Let's fix that.

647fe7a47a doc: dts/macros.rst: "clocks" macro fixes
The "fixed-clock" value referenced in the documentation is actually a
compatible value, not a property name. Fix that.

Harden the "expected to have a clock-frequency property" language to
use "must" instead of "expected". The scripts error out if a node with
fixed-clock compatible is missing a clock-frequency property; it's not
a soft expectation.

Be explicit about clock-frequency units.

6648fe428a doc: devicetree: Update outdated diagram and mention zephyr.dts
zephyr_dt_inputs_outputs.svg still shows the output from dtc being used,
but dtc is unused (except for finding warnings/errors) after the old
devicetree scripts were removed in commit c8c35f76ab ("scripts: dts:
Remove deprecated extract_dts_includes.py script").

Update zephyr_dt_inputs_outputs.svg to show how things are done now.
Also include the new zephyr.dts debugging aid in it. Tweak the
formatting a bit too.

Add zephyr.dts to the diagram in the build overview section too, and
mention zephyr.dts in the text of the devicetree and build overview
pages.

Remove zephyr_dt_inputs_outputs.png and use zephyr_dt_inputs_outputs.svg
directly. Many other places the documentation include SVGs directly, and
there haven't been any complaints, so it probably works fine. The .png
and .svg versions had also drifted out of sync.

Piggyback a link from the devicetree page to the build overview page, to
make it easier to discover.

(I used draw.io to update the diagrams.)

31822c6d5b doc: kconfig: Explain why zephyr/.config assigns promptless symbols
I think a lot of the confusion with promptless symbols being assigned
might come from opening zephyr/.config, seeing that it assigns a bunch
of promptless symbols, and assuming that Kconfig must respect those
assignments, even though it doesn't.

Explain why zephyr/.config assigns promptless symbols (it's because it
doubles as configuration output). That should clarify things a bit.

Diagram and text improvements:

 - Redraw the configuration phase diagram to better reflect the actual
   logic. Remove some misleading arrows, like from devicetree.h to
   Kconfig. Kconfig uses the devicetree scripts directly.

 - After the old devicetree scripts were removed in commit c8c35f76ab
   ("scripts: dts: Remove deprecated extract_dts_includes.py script"),
   the dtc compiler is only run to catch any high-level warnings and
   errors from it. The output is unused.

   Update the diagram and descriptions to explain how dtc is used.

 - Mention kconfigfunctions.py and explain better how devicetree and
   Kconfig interact

 - Clarify that 'cpp' is the C preprocessor. People often confuse it
   with C++.

 - Fix a typo'd devicetree_fixups.h in the text

 - Use the :file: role for files instead of italic text

 - Add links to the devicetree and Kconfig sections of the manual, and
   use the :zephyr_file: role to turn more files into direct links

 - Make the text generic re. Make vs. Ninja

4e85006ba4 dts: Rename generated_dts_board*.{h,conf} to devicetree*.{h,conf}
generated_dts_board.h is pretty redundant and confusing as a name. Call
it devicetree.h instead.

dts.h would be another option, but DTS stands for "devicetree source"
and is the source code format, so it's a bit confusing too.

The replacement was done by grepping for 'generated_dts_board' and
'GENERATED_DTS_BOARD'.
