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.
