Tatenda Chipeperekwa f3b2c5f89c disp: msm: dp: add support for Trusted UI transitions ...

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
