Startup power domains according to the expected final state given the
power supply and PM device runtime support.

Let the driver compile without `PM_DEVICE_POWER_DOMAIN`, in which case
the driver only controls the GPIO, without notifying dependant devices.

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.

Changing function call order. We need to first power-up the power domain
before we turn on the devices.

Only run the `PM_DEVICE_ACTION_TURN_ON` and `PM_DEVICE_ACTION_TURN_OFF`
actions for child devices that have refered to the domain via the
`power-domain` property.
This prevents multiple actions being run for devices that refer to
several power domains, e.g.
```
test_dev: test_dev {
compatible = "test-device-pm";
status = "okay";
power-domain = <&test_reg_1>;
alternate-domain = <&test_reg_chained>;
};
```

This patch contains several small changes to the intel adsp power
domain.
- include missing header,
- replacing sys_write32/sys_read32 with sys_write16/sys_read16 since
DfPWRCTL is a 16 bit register,
- renaming struct to be more representing what it is,
- passing register address, not a value to the sys_read/sys_write
functions,
- pd_intel_adsp_init is now returning actual status.

Update power_domain drivers to use DT_HAS_<compat>_ENABLED Kconfig
symbol to expose the driver and enable it by default based on
devicetree.
We remove one reference in prj.conf that is no longer needed.

Improve the power domain logging by making the log level configurable
and boosting the log level of the messages printed when the domain turns
on and off.

Update the Zephyr include paths to be compatible with removing
`CONFIG_LEGACY_INCLUDE_PATH` in the future.

Respect the configured values for how long the domain takes to turn on,
and how long the domain needs to be off for before it can be repowered.
As these actions can block, guard the transition function with
pm_device_action_can_block. To avoid system PM being able to turn the
domain off but not back on again, guard the entire implementation.

Move the `pm_device_runtime_init_*` functions from <pm/device_runtime.h>
to <pm/device.h>. The initial device state should be settable
independently of whether `CONFIG_PM_DEVICE_RUNTIME` is enabled.
This also resolves a compilation error when attempting to use these
functions without also including <pm/device.h>.
Function documentation is also updated to be more general than only
referencing runtime PM, as this also applies to system PM and manually
run actions.

Initial implementation of a simple GPIO controlled power domain.
It exposes no API of its own, all functionality is contained inside
the runtime power management callbacks.
