Keith: this version completes the IvyBridge support :)
Bossart: hotplug is working fine now, with some minor issues:
- on G45, monitor hot removal is not handled at all in
i915_driver_irq_handler(). I'll leave it as a future TODO.
- on IvyBridge, _repeated_ plug/unplug will trigger
[ 1183.654859] ALSA hda_eld.c:259 HDMI: Unknown ELD version 0
which means the ELD_valid flag will be seen by audio driver,
however it cannot get any valid ELD data. I double checked and
find everything in the graphics driver is working as expected:
ironlake_write_eld() is writing the good ELD data to the same
pipe on hot plug events. So I'll leave it as a possible bug of
the early stage hardware.
