The devicetree link is rendering as "Devicetree Guide" instead of
"devicetree". Fix that.
My guess is that most users won't care about the details of the
requirements, and rather just want to know if their board is supported
or not. So move the error you'll see on unsupported boards before the
details about how to add support (which involve a pretty significant
learning curve).
Also mention overlays as a way to get this working.

This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point
library).
Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.

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).

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

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.
