List of improvements:
- The PM logging module was only available if CONFIG_PM=y, however, it
was also used by Device PM (which can be selected without PM). A new
logging module has been created for Device PM.
- Log level is passed to LOG_MODULE_(DECLARE|REGISTER)
- Logger name has been adjusted to `pm` (was `power`)

POLL is not a dependency of runtime device PM since it now uses
conditional variables to notify waiting threads.

Uses the stats subsys to provide simple but useful debugging stats for
power management state changes and timing.
Removes the no longer needed PM_DEBUG config option
Replaces the use of PM_DEBUG for a test clock output pin for mec1501 and
adds in its place an SoC Kconfig option to enable it.
Adds a STATS_SET macro for assigning a value to a stat group field

When a device is defined a new pointer to a device will be created in
the "z_pm_device_slots" region, effectively creating a device array with
the same size as the number of system devices. This array is then used
by the device PM subsystem to keep track of suspended devices during
power transitions.
