Additional test to check if getting a device while there
is a pending async put does not trigger unnecessary device

Add a delay parameter to asynchronous device runtim put. This allows
to delay the put operation what is useful to avoid multiple states
transitions.

In some platforms it may be desirable to disable certain CPU power
states, for example, because they have extra requirements not available
on all boards/applications. Because `cpu-power-states` are defined at
SoC dts file levels, the only way to achieve that now was by re-defining
`cpu-power-states` property in e.g. a board file. With this patch, one
can now selectively set `status = "disabled";` to any power state and it
will be skipped by the PM subsystem.

Device dependencies are not always required, so make them optional via
CONFIG_DEVICE_DEPS. When enabled, the gen_device_deps script will run so
that dependencies are collected and part of the final image. Related
APIs will be also made available. Since device dependencies are used in
just a few places (power domains), disable the feature by default. When
not enabled, a second linking pass will not be required.

Events in the power-management policy context are defined as any source
that will wake up the system at a known time in the future. By
registering such event, the policy manager will be able to decide wether
certain power states are worth entering or not.
Events will bypass the ticks argument received by the policy manager if
they occur earlier.

- Reduce "extra" added latency when trying to enter light
sleep from 500ms to 50us, since light sleep states
(e.g. "WFI idle") usually have microsecond-range residency
times.
- Keep "extra" latency when entering deep sleep the same at
1100ms (as we're trying to enter the deepest sleep state
available, it doesn't hurt).
- Replace k_uptime_delta() with manual subtraction since
k_uptime_delta() updates starting timestamp which leads to
incorrect timing measurement when k_uptime_delta() is
called for the second time.
- Measuring PM sleep entry latency using pm_notifier entry
callback, do it only for the first PM entry event after
calling k_usleep(), as during the sleep PM entry & exit
may happen multiple times and that is normal.
