section 1.1.1 Display Diagram. This is not exactly sandy bridge but it
gives a good overview.

for displayport aux channel stuff, i dont think you need the FDI enabled,
just the clocks. Also dont attempt to modeset, all we want is just read
the EDID info over the displayport aux channel. Once we have that, setting
the right port is done automatically.

Note, without the DP AUX channel working, you wont get anything, because
displayport link training is controlled over it.
