[Why] HDMI 2.0 adds aspect ratio attribute to distinguish different 4k modes. 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.
[How] Inherit Ville Syrjälä's work "drm/edid: Prep for HDMI VIC aspect ratio" at https://patchwork.kernel.org/patch/11174639/
Add picture_aspect_ratio attributes to edid_4k_modes[] and construct VIC and HDMI_VIC by taking aspect ratio into consideration.

Our CI didn't complain about anything that looked relevant, so I went ahead an pushed these to drm-misc-next.
Thanks for the patches.
