The vrefresh field of the mode is 0 for most modes
fetched from the EDID (e.g., established timings).
When dealing with monitors that have a bogus preferred
mode, we may not always select the mode we want because
we compare the target refresh to the mode's vrefresh which
is 0 in a lot of cases.

The conflict in intel_drv.h tripped me up a bit since a patch in dinq
moves all the functions around, but another one in drm-next removes a
single function. So I'ev figured backing this into a backmerge would
be good.
i915_dma.c is just adjacent lines changed, nothing nefarious there.

This allows us to use fewer bits in the mode structure, leaving room for
future work while allowing more stereo layouts types than we could have
ever dreamt of.
I also exposed the previously private DRM_MODE_FLAG_3D_MASK to set in
stone that we are using 5 bits for the stereo layout enum, reserving 32
values.
Even with that reservation, we gain 3 bits from the previous encoding.
The code adding the mandatory stereo modes needeed to be adapted as it was
relying or being able to or stereo layouts together.

When scanning out a stereo mode, the AVI infoframe vic field has to be
the underlyng 2D VIC. Before that commit, we weren't matching the CEA
mode because of the extra stereo flag and then were setting the VIC

We'll need the HDMI OUI for the HDMI vendor infoframe data, so let's
move the DRM one to hdmi.h, might as well use the hdmi header to store
some hdmi defines.
(Note that, in fact, infoframes are part of the CEA-861 standard, and
only the HDMI vendor specific infoframe is special to HDMI, but
details..)
