Merge branch 'device-properties' 

* device-properties:
  device property: Introduce firmware node type for platform data
  device property: Make it possible to use secondary firmware nodes
  driver core: Implement device property accessors through fwnode ones
  driver core: property: Update fwnode_property_read_string_array()
  driver core: Add comments about returning array counts
  ACPI: Introduce has_acpi_companion()
  driver core / ACPI: Represent ACPI companions using fwnode_handle
