The OSVR virtual reality headset HDK 2.0 uses a different EDID
vendor and device identifier than the HDK 1.1 - 1.4 headsets.
Add the HDK 2.0 vendor and device identifier to the quirks table so
that window managers do not try to display the desktop screen on the
headset display.

I don't know how many of these VR headsets are still around but I have a
working one and I saw an entry for HDK 1.x so I thought it would be good
to add HDK 2.0.

v2: The vendor ID was byte swapped.
I'm not sure how I missed that in v1.
