    drm/i915: report Gen5+ CPU and PCH FIFO underruns

Do the fifo underrun reports fire up?

Also, as discussed in the meeting can you please test what happens when you set
the panel to eDP? Without that we also set up the HDMI connector, and the i2c
probing over HDMI is known to kill some eDP panels ...
