The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.
To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.
This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

Change the common "init with 0" + "give" idiom to "init with 1". This

ever so slightly.
This change has been performed mechanically with the following

This commit removes unnecessary CONFIG_SYS_POWER_DEEP_SLEEP protection
in shim drivers as QMSI 1.4 has introduced empty context save/restore
functions that can be called in Quark D2000, therefore keeping common

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.

deprecated.
New init levels introduced: PRE_KERNEL_1, PRE_KERNEL_2, POST_KERNEL
to replace them.
Most existing code has instances of PRIMARY replaced with PRE_KERNEL_1,
SECONDARY with POST_KERNEL as SECONDARY has had a longstanding bug
where the documentation specified SECONDARY ran before the kernel started
up, but actually ran afterwards.

Add type cast to prevent overflow.
In the pwm driver function pwm_qmsi_get_cycles_per_sec(),
there is a multiplication which takes ticks_per_us (32 bit
unsigned integer) and USEC_PER_SEC. Practically, overflow
will not happen, since the sys clock is not that high. But,
it can trigger an overflow alarm by automatic tools.

Implement qmsi shim driver based on the new API interfaces.
Recently, a RFC was sent and discussed on the re-design of
PWM interfaces. A API change was already posted.
The API new design will deprecate all existing APIs and three
new APIs will be added. The new APIs are pwm_pin_set_cycles,
pwm_pin_set_usec and pwm_get_cycles_per_sec. Pwm_pin_set_cycles
and pwm_pin_set_usec will rely on two driver functions to set
the period and pulse width. This change is to implement the
driver functions pwm_qmsi_pin_set and pwm_qmsi_get_cycles_per_
sec.

Update the QMSI drop we maintain in Zephyr, and fix the build where
needed:
- QM_SCSS_INT is renamed to QM_INTERRUPT_ROUTER;
- every member of QM_INTERRUPT_ROUTER was renamed as well;
- QM_IRQ_* renamed too, mostly added _INT at the end;
- some isr functions were renamed to keep their names consistent;
- build for x86 needs to define QM_LAKEMONT, as QM_SENSOR was for ARC.

When user wants to set all the PWM ports in one call,
pwm_qmsi_set_values() should call __set_one_port() for
each PWM port. The current pwm_qmsi_set_values() will
return after setting the first PWM port. It's illogical.

The new device control API added a 'device_power_state' variable to the
driver's data structure to keep track of the current power state set
for a device. This member variable is conditionally built into the
runtime data structure of each driver, but in some cases the whole data
structure is conditional on its respective API_REENTRANCY config
variable.
In those cases where the runtime data was previously used only for
reentrancy protection, the runtime data pointer used for device
initialization is NULL, and when power management is enabled, this
invalid pointer ends up dereferenced to get the device_power_state
member.
Make the declaration of the runtime data dependent on any of its
conditional members, and NULL only when all of those settings are
disabled.
