Finally I have chances to look at the specs and I am not sure if this
solution fully reflects the specs and is scalable. According to specs
VIC set to 0 in AVIF means "Video Format not documented in CTA-861", ie
it is described by vendor specific data block and vendor specific
infoframe, maybe something else(???). I suppose ideally during EDID read
there should be recorded info for every mode if it was defined by vendor
extension, or not. This info could be later used by drivers to configure
AVIF and VSIF accordingly.

Anyway as a short-term initial solution it could work.
So:
