Several reviewers agreed that DT_HAS_NODE_STATUS_OKAY(...) was an
undesirable API for the following reasons:
- it's inconsistent with the rest of the DT_NODE_HAS_FOO names
- DT_NODE_HAS_FOO_BAR_BAZ(node) was agreed upon as a shorthand
for macros which are equivalent to
DT_NODE_HAS_FOO(node) && DT_NODE_HAS_BAR(node) &&
- DT_NODE_HAS_BAZ(node), and DT_HAS_NODE_STATUS_OKAY is an odd duck
- DT_NODE_HAS_STATUS(..., okay) was viewed as more readable anyway
- it is seen as a somewhat aesthetically challenged name
Replace all users with DT_NODE_HAS_STATUS(..., okay), which is
semantically equivalent.
This is mostly done with sed, but a few remaining cases were done by
hand, along with whitespace, docs, and comment changes. These special
cases include the Nordic SOC static assert files.

Rename DT_HAS_NODE to DT_HAS_NODE_STATUS_OKAY so the semantics are
clear. As going forward DT_HAS_NODE will report if a NODE exists
regardless of its status.

Following other drivers, Kconfig based instances are now entirely
removed. In order to do this change, PWM nodes in board DT files have
been given a pwm{N} label so that both:
- DT API checks such as #if DT_HAS_NODE(DT_NODELABEL(pwmN)) can be
used (N being PWM instance number).
- DT references can be written as pwms = <&pwmN x y>; instead of
pwms = <&{/soc/timers@XXXXXXXX/pwm} x y>;
This approach is also used on the Linux Kernel.

Following conversion of stm32 i2c driver to use of DT_NODELABEL
macros, configuration of i2c instance in stm32 boards should
no more be done thanks to Kconfig symbols, but is done thanks
to device tree file.
Clean boards files from these symbols.

Enables PWM support using the built-in red LED. Tested with:
- samples/basic/blink_led
- samples/basic/fade_led
Signed-off-by: Gerard Marull-Paretas <gerard@teslabs.com>
Only basic support has been added as some drivers require some fixes.
I have successfully tested the following examples:
- samples/hello_world
- samples/basic/blinky
- samples/basic/button
