Enables PWM support using the built-in red LED. Tested with:
- samples/basic/blink_led
- samples/basic/fade_led

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.

Remove leading/trailing blank lines in .c, .h, .py, .rst, .yml, and
.yaml files.
Will avoid failures with the new CI test in
https://github.com/zephyrproject-rtos/ci-tools/pull/112, though it only
checks changed files.
Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst
to get rid of the trailing blank line there. It was probably misplaced.

Commit 16d8ce519c introduced changes
that caused this sample to no longer behave according to documentation
and for some hardware to no longer work at all.
On nRF51 SoCs for instance, the reported number of cycles per second
is 16M, what makes the calculated max_period and min_period to be 16
and 0 microseconds, respectively, what effectively makes it impossible
for the sample to return to the initial blinking frequency. Moreover,
with such short PWM periods, the blinking is not even noticeable.
This patch partially reverts the changes mentioned above, and instead
of calculating max_period and min_period basing on the reported clock
rate, it tries to only decrease the max_period if needed, accordingly
to what the used hardware can handle.
Documentation is also updated to mention the possible change in
observed behavior of the sample on some hardware.

Cleanup references to boards in some of the example and use the same
boards through the examples. Other minot cleanups and make the text more
generic and not specific to certain boards.

Supported PWM at pins A0, D3, D5 and D6 which are also Arduino
compatible. Also the onboard red LED can be used with PWM.
The basic/{fade_led, blink_led} samples to apply to this board
seemlessly and operate on the onboard red LED.
Also supported RTC.

Since the Arduino 101 and the Quark SE C1000 are not actively developed
boards, default to other boards that are maintained and used.

Add support for nRF boards by using the software-based PWM driver. The
prescaler has to be configured so that the clock runs slower in order to
make the on-board LED blink in the way it is described in the Readme.

The hexiwear_k64 board can drive the leds with a pwm, so update the
blink_led sample to work with this board. Reduces the maximum blinking
frequency from 500 Hz to 64 Hz because your eye can't distinguish these
higher frequencies (the led appears solidly on). Increases the minimum
blinking frequency from 0.5 Hz to 1 Hz because the mcux pwm driver can't
handle frequencies less than 1 Hz.

Docs need a label at the top so we can use :ref:`labelname`
to create a link to that doc from other docs.

The headings on some .rst files were not following the expected
heading order of using # for h1, * for h2, = for h3, and - for h4
This patch fixes that, and the doc/templates/*.tmpl files created
for folks to use as templates for creating board and sample docs.
