drm: handle HDMI 2.0 VICs in AVI info-frames

Browse Source 
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 if the connected display is HDMI 2.0.
- HDMI infoframes carry one of this two type of information:
	- VIC for 4K modes for HDMI 1.4 sinks
	- S3D information for S3D modes
  As CEA-861-F has already defined VICs for 4K videomodes, this
  patch doesn't allow sending HDMI infoframes for HDMI 2.0 sinks,
  until the mode is 3D.

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

V2: Rebase, Added r-b from Andrzej
V3: Addressed review comment from Ville:
	- Do not send VICs in both AVI-IF and HDMI-IF
	  send only one of it.
V4: Rebase
V5: Added r-b from Neil.
    Addressed review comments from Ville
    - Do not block HDMI vendor IF, instead check for VIC while
      handling AVI infoframes
V6: Rebase
