Update: Just tested DP and its working!
However, it's found that hot plug under X won't work...
The previous hot plug tests are done in KMS console which are all fine: on re-inserting the monitor, ->mode_set will be called and HDMI/DP audio will be re-enabled and ELD be transfered.
However when in X, ->mode_set won't be called at all. Only ->get_modes and ->detect are called...
Thanks, Fengguang

Sorry forgot to remove this left over chunk...
Note that I've not yet got the hardware to test the DisplayPort part of this patch, but should be able to do so this week.
