The CRTC_STEREO_DOUBLE_ONLY define was introduced in commit:
commit ecb7e16bf187bc369cf6a5cd108582c01329980d

drm: add helper to get crtc timings (v5)
but if we want the stereo h/v adjustments, we need to set the
CRTC_STEREO_DOUBLE flag. Otherwise, we'll get the wrong h/v for frame packing
stereo 3d modes.
