The API spec states that calling pin_set() with period set to 0 is
equivalent to set the PWM channel to an inactive level. Some drivers
treat this input as invalid (-EINVAL), however, it's an unsupported
feature. Maybe it's due to copy&paste effect? This changes error message
to be clear and changes return value to -ENOTSUP for this case.

The API call checks for this condition before calling the pin_set driver
OP call, so drivers don't have to do this check now.

Usually, we want to operate only on "available" device
nodes ("available" means "status is okay and a matching binding is
found"), but that's not true in all cases.
Sometimes we want to operate on special nodes without matching
bindings, such as those describing memory.
To handle the distinction, change various additional devicetree APIs
making it clear that they operate only on available device nodes,
adjusting gen_defines and devicetree.h implementation details
accordingly:
- emit macros for all existing nodes in gen_defines.py, regardless
of status or matching binding
- rename DT_NUM_INST to DT_NUM_INST_STATUS_OKAY
- rename DT_NODE_HAS_COMPAT to DT_NODE_HAS_COMPAT_STATUS_OKAY
- rename DT_INST_FOREACH to DT_INST_FOREACH_STATUS_OKAY
- rename DT_ANY_INST_ON_BUS to DT_ANY_INST_ON_BUS_STATUS_OKAY
- rewrite DT_HAS_NODE_STATUS_OKAY in terms of a new DT_NODE_HAS_STATUS
- resurrect DT_HAS_NODE in the form of DT_NODE_EXISTS
- remove DT_COMPAT_ON_BUS as a public API
- use the new default_prop_types edtlib parameter

Remove semicolon between instance invocations of DT_FOREACH_IMPL_ and
thus DT_INST_FOREACH. This provides more flexibility to the user. This
requires we fixup in tree users to add semicolon where needed.

Make drivers multi-instance wherever possible using DT_INST_FOREACH.
This allows removing DT_HAS_DRV_INST in favor of making drivers just
do the right thing regardless of how many instances there are.
There are a few exceptions:
- SoC drivers which use CMake input files (like i2c_dw.c) or otherwise
would require more time to convert than I have at the moment. For the
sake of expediency, just inline the DT_HAS_DRV_INST expansion for
now in these cases.
- SoC drivers which are explicitly single-instance (like the nRF SAADC
driver). Again for the sake of expediency, drop a BUILD_ASSERT in
those cases to make sure the assumption that all supported SoCs have
at most one available instance is valid, failing fast otherwise.

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.

We generated a define for each instance to convey its existance of the
form:
#define DT_<COMPAT>_<INSTANCE> 1
However we renamed all other instance defines to be of the form
DT_INST_<INSTANCE>_<FOO>. To make things consistent we now generate a
define of the form:
#define DT_INST_<INSTANCE>_<COMPAT> 1
We also now deprecate the DT_<COMPAT>_<INSTANCE> form and fixup all uses
to use the new form.

This patch adds basic support for the PWM devices available on the Atmel
SAM family. Beside enabling the driver, everything is selected through
the device tree, including enabling the PWM0 and PWM1 devices. Thus
CONFIG_PWM_0 and CONFIG_PWM_1 are ignored.
