Fix notifications for USB PD enabled devices
The devices with USB PD support can have the data role and the power role of
their USB-C port reversed. Ensure the title of the notification and the content
of the USB selection dialog is correct in this case.
Testing done on Ryu with the following accessories:
- legacy A-C cable
- USB-C charger (5X)
- USB-PD charger (Zinger)
- Pixel 2 (in both roles)
- Type-C Macbook (in both roles)
- Nexus 5X (in both roles)
- Apple AV HDMI accessory
- LG USB-C screen/dock
- Honeybuns dock
