HDMI 1.4b support the CEA video modes as per range of CEA-861-D (VIC 1-64). For any other mode, the VIC filed in AVI infoframes should be 0. HDMI 2.0 sinks, support video modes range as per CEA-861-F spec, which is extended to (VIC 1-107).
This patch adds a bool input variable, which indicates if the connected sink is a HDMI 2.0 sink or not. This will make sure that we don't pass a HDMI 2.0 VIC to a HDMI 1.4 sink.
This patch touches all drm drivers, who are callers of this function drm_hdmi_avi_infoframe_from_display_mode but to make sure there is no change in current behavior, is_hdmi2 is kept as false.
In case of I915 driver, this patch checks the connector->display_info to check if the connected display is HDMI 2.0.

PS: This patch touches a few lines in few files, which were already above 80 char, so checkpatch gives 80 char warning again.

As far as I remember, we decided to send VICs > 64 to HDMI 2.0 monitors only. If you can provide some more thoughts about how can we make it better ?
The question is whether we send the VIC in the AVI infoframe of the HDMI infoframe. IIRC sending both isn't legal, and I think we might have concluded that we might have to pass the AVI infoframe to the HDMI infoframe construction function or vice versa to figure out which gets sent.
