Pull device properties framework updates from Rafael Wysocki:
 "These add helpers for counting items in a property array and extend
  the "software nodes" support to be more convenient for representing
  device properties supplied by drivers and make the intel_cht_int33fe
  driver use that.

  Specifics:

   - Add helpers to count items in a property array (Andy Shevchenko).

   - Extend "software nodes" support to be more convenient for
     representing device properties supplied by drivers (Heikki
     Krogerus).

   - Add device_find_child_by_name() helper to the driver core (Heikki
     Krogerus).

   - Extend device connection code to also look for references provided
     via fwnode pointers (Heikki Krogerus).

   - Start to register proper struct device objects for USB Type-C muxes
     and orientation switches (Heikki Krogerus).

   - Update the intel_cht_int33fe driver to describe devices in a more
     general way with the help of "software nodes" (Heikki Krogerus)"
