Add support for requesting an inverted PWM pulse (active-low) when
setting up the period and pulse width of a PWM pin. This is useful
when driving external, active-low circuitry (e.g. an LED) with a PWM
signal.
All in-tree PWM drivers is updated to match the new API signature, but
no driver support for inverted PWM signals is added yet.
All in-tree PWM consumers are updated to pass a flags value of 0
(0 meaning default, which is normal PWM polarity).
Fixes#21384.

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.

Instead of having a mix of west and CMake/ninja instructions for
building and flashing, document it using only west. This will help
clarify that west is the default build tool in Zephyr and should also
reduce confusion over what tool to use.

doc/extensions/zephyr/application.py for :tool:, from all to west.

The maximum period a PWM controller can generate depends on its input
clock and its resolution (16-bit, 32-bit...). Setting a 1s max period
generates error with some hardwares (mimxrt1064_evk) because of clock
limitation.
This patch fixes this issue by calculating maximum period of the PWM
device to adjust max and min periods accordingly.

When tickless is available, all existing devices can handle much
higher timing precision than 10ms. A 10kHz default seems acceptable
without introducing too much range limitation (rollover for a signed
time delta will happen at 2.5 days). Leave the 100 Hz default in
place for ticked configurations, as those are going to be special
purpose usages where the user probably actually cares about interrupt
rate.
Note that the defaulting logic interacts with an obscure trick:
setting the tick rate to zero would indicate "no clock exists" to the
configuration (some platforms use this to drop code from the build).
But now that becomes a kconfig cycle, so to break it we expose
CONFIG_SYS_CLOCK_EXISTS as an app-defined tunable and not a derived
value from the tick rate. Only one test actually did this.

YAML document separators are needed e.g. when doing
$ cat doc1.yaml doc2.yaml | <parser>
For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.
Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).
The replacement was done with
$ git ls-files '*.yaml' | \
xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'
First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.
Some redundant blank lines at the end of files were cleared with
$ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'
This is more about making sure people can understand why every part of a
binding is there than about removing some text.
