d67a5786bc pm: device_runtime: Change API behavior s/_sync/_async
Most APIs have the default synchronous and an asynchronous version
with the sufix _async because that is the most common use.

All devices in tree right now are using the synchronous version, so
just change it to be consistent with the rest of the system.

c524075780 pm: runtime: rename API with pm_device prefix
Use `pm_device_*` prefix for the device runtime PM API. This adds the
API to the `pm` namespace, making it clear part of the PM subsystem.

25bb163dc2 pm: reorganize headers
- Move PM related APIs to `include/pm` so that it follows API `pm_`
  prefix namespace. In order to make transition easier
  `include/power/power.h` is kept pointing to `include/pm/pm.h`.
- Move most of device PM related content from `include/device.h` to
  `include/pm/device.h` and `include/pm/runtime.h`.
