I tried enabling the second screen through the kernel command line parameters (video=HDMI-1:e video=HDMI-2:e) and running xrandr.  This is my output from xrandr -q

Currently the code assumes that port C is eDP, not DP/HDMI. The specs
say that physically either port should be able to function in any role
(eDP/DP/HDMI).

Not sure if there's some way to detect which way the board is wired
(some VBT stuff like the eDP on port D on HSW?), or maybe we should
just register the DP/HDMI ports if eDP init fails?
