Device initialization may require use of generic services such as
starting up power rails, some of which may be controlled by GPIOs on
an external controller that can't be used until full kernel services
are available. Generic services can check k_is_in_isr() and mediate
their behavior that way, but currently have no way to determine that
the kernel is not available.
Provide a function that indicates whether initialization is still in
pre-kernel stages where no kernel services are available.

move misc/printk.h to sys/printk.h and
create a shim for backward-compatibility.
No functional changes to the headers.
A warning in the shim can be controlled with CONFIG_COMPAT_INCLUDES.

device_get_binding() compares pointers first before doing strcmp().
However, enabling coverage forces -O0 to disable any compiler
optimizations. There would be multiple copies of the same string,
and the code pathing doing pointer comparsion would not be tested
at all. So add this flag to merge string constants such that
the pointer comparison would be exercised.
This also adds a bad driver which fails initialization. This is
to make sure that execution path is covered.

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.

Set device state to DEVICE_PM_ACTIVE_STATE before making it busy.
Also improves the kernel/device.c coverage.

Also parse test documentation. When add tests to doxygen, we get
warnings about device.h macros not being defined. Exclude this now and
track this in issue #7367.

Instead of completely excluding those tests, mark them as skipped and
provide an noop function that marks the test as skipped where test is
not supported.

Split the search into two loops: in the common scenario, where device
names are stored in ROM (and are referenced by the user with CONFIG_*
macros), only cheap pointer comparisons will be performed.
Reserve string comparisons for a fallback second pass.
