The eDP panel must be powered up for aux transactions, so power it

- only mess with eDP panel on DCE4+
- only mess with eDP panel on eDP connectors, not all DP connectors
v3:

If there was no connector mapped to the encoder, atombios_get_encoder_mode()

The hw stores a default clear state for registers in the context
range that can be initialized when the CP is set up.  Set the
