Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Re-design the pwm API interfaces. A RFC was sent and discussed
recently on the re-design of PWM APIs.
APIs like pwm_pin_set_values, pwm_pin_set_period, pwm_pin
_set_duty_cycle will be deprecated and replaced by the new
APIs pwm_pin_set_cycles and pwm_pin_set_usec.
A new API pwm_get_cycles_per_sec will be added to get the
clock rate for pwm pins.
The API pwm_pin_set_phase will be deprecated(it always sets
the phase to zero).
The API pwm_pin_configure will be deprecated since it is not
doing anything for most of the platforms or it can be moved
to device init function for the other platforms.
All the pwm_all_xxx APIs will be deprecated. If necessary,
user or an app can set the pins individually.

Correct the argument definition inconsistency for the set
value API. To be consistent with other pwm sub drivers, the
on and off arguments for the set value api are re-defined.
On: how far (number of timer count) from the beginning of a PWM
cycle the PWM pin will be asserted.
Off:how far (number of timer count) from the beginning of a PWM
cycle the PWM pin will be de-asserted.

Drivers that implement power management should use the preferred
device_pm_ops method instead.

Some function *typedefs* confuse the *Sphynx* / *breathe* parser [see
the patch for full details]. Implement a workaround (defining the name
with @typedef), add workaround documentation and file a bug with the
sphinx/breathe developers.

The param "pwm" is not in the argument list of pwm_all_set_phase().
So remove it.

This patch replaces all occurences of the macro DEV_INVALID_OP by
-ENOTSUP at the driver level. So this patch touch the files under
drivers/, include/ and samples/drivers/ when applicable.
This patch is part of the effort to transition from DEV_* codes to
errno.h codes.
