Successfully communicate SVDM for discovery (identity, svids, modes)
and enter mode.
Still need to:
- Add same functionality on when power role is sink too.
- determine what connected events would require exit mode.
- do proper cleanup on disconnect.
- implement real display port 'enter' mode for samus_pd
- test & cleanup
Additionally the USB Billboard class functionality needs to be added
but will likely do that in a separate CL.
