xhci: ext-caps: Use software node API with the properties

This replaces the platform_device_add_properties() call with
the safer device_create_managed_software_node() that does
exactly the same, but can also guarantee that the lifetime
of the node that is created for the device is tied to the
lifetime of device itself.
