drm/edid: detect color formats and CTA revision in all CTA extensions

Browse source

Convert drm_find_cea_extension() to EDID block iterator in color format
and CTA revision detection. Detect them in all CTA extensions.

Also parse CTA Data Blocks in DisplayID even if there's no CTA EDID
extension.

v2:
- Don't assume DRM_COLOR_FORMAT_RGB444 support if there's only DisplayID
  CTA Data Blocks (Ville)
