We add support for Trusted UI (TUI) transitions and address the
following use cases:
1. Display was active before TUI start
- Power off on TUI start, power off on TUI stop
- Register access not allowed after TUI start (skip all
events except disconnect)
2. Hotplug while TUI is active
- Connect: skip sending connect uevent
- Disconnect: send disconnect uevent and skip any controller
programming
3. TUI start while processing HPD High
- Complete all connect work (and therefore any register access)
then send connect uevent
4. Audio
- Disable audio at TUI start and skip audio programming if TUI
is active
