drm/edid: split HDMI VSDB info and mode parsing
Separate the parsing of display info and modes from the HDMI VSDB. This
is prerequisite work for overall better separation of the two parsing
steps.
The info parsing is about figuring out whether the sink supports HDMI
infoframes. Since they were added in HDMI 1.4, assume the sink supports
HDMI infoframes if it has the HDMI_Video_present bit set (introduced in
HDMI 1.4). For details, see commit f1781e9bb2dd ("drm/edid: Allow HDMI
infoframe without VIC or S3D").
The logic is not exactly the same, but since it was somewhat heuristic
to begin with, assume this is close enough.
v2:
- Simplify to only check HDMI_Video_present bit (Ville)
- Drop cea_db_raw_size() helper (Ville)
