This patch adds a bool variable (is_hdmi2_src) in the drm connector structure. While handling the EDID for HDMI 2.0 sinks, its important to know if the source is HDMI 2.0 capable or not, so that a lot of work can be done/bypassed based on this information. One such example is adding YCBCR420 only modes. If the driver knows that this source is not HDMI 2.0 capable, it will not add YCBCR420-only modes while adding EDID modes, and will prevent any runtime modeset failures. This variable will be initialized from I915 driver in the next patch and will be used in the EDID handling for HDMI 2.0 specific features, in this same series.
