In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

The variable indicating the PWM channel is now names "channel" instead
of "pwm", adjust all drivers.

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.

Convert pwm drivers to use new DT variants of the DEVICE APIs.

Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.
A coccinelle rule is used for this:

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.

The TPM (Timer/PWM Module) is a 2- to 8-channel timer which supports
input capture, output compare, and the generation of PWM signals to
control electric motor and power management applications.
This patch adds the driver and the binding necessary for instantiating
the driver. The work is based on the RV32M1 driver for TPM done by
Henrik Brix Andersen. A later patch will enable this driver to be used
for the KW41Z SoC, if PWM support is requested.
