According to Appendix E of HDMI 2.0 spec, source should use VSIF to indicate video mode only when the mode is one defined in HDMI 1.4b 4K modes. Otherwise, use AVI infoframes to convey VIC. Current code doesn't take aspect ratio into consideration while constructing avi infoframe. Should modify that.
