[Nouveau] [PATCH 0/6] drm/nouveau: Enable HDMI Stereoscopy

This is an initial implementation of HDMI 3D mode support for the
nouveau kernel driver.  It works on all of the hardware that I have
available to test at the moment, but I am unsure as to the overall
approach taken for setting HDMI InfoFrames, there's no support for g84
or gf119 disps, and the criteria for enabling stereo support for an
output seems a bit iffy.

The first four patches arrange to set the HDMI InfoFrames for gt215
and gk104 disps, and provide the parsing side of support for g84 and
gf119 disps.

The fifth patch removes code that sets up the "mandatory" 3D modes.
The requirement is that a display that supports 3D support at least
one of these modes, not that it must support all of them.

The sixth patch enables stereo support on all TMDS outputs, and adds a
term (copied from the i915 driver) to adjust the clock required for
frame-packed stereo modes.  The criteria used here for enabling stereo
on an output seems wrong to me, but it's the least wrong thing that
I've been able to come up with so far.

Even just taking the InfoFrame patches and leaving the stereoscopy
patches until the rest of the InfoFrame support is worked out would
probably be a win.
