Pull device properties framework updates from Rafael Wysocki:
 "These mostly rearrange the device properties core code and add a few
  helper functions to it as a foundation for future work.

  Specifics:

   - Rearrange the core device properties code by moving the code
     specific to each supported platform configuration framework (ACPI,
     DT and build-in) into a separate file (Sakari Ailus).

   - Add helper functions for accessing device properties in a
     firmware-agnostic way (Sakari Ailus, Kieran Bingham)"
