Now that we have all the VICs in info->vics, use them to simplify access
based on VIC index, i.e. on the order of VICs in the EDID, and avoid
passing CTA VDB pointers around.

This also fixes the highly unlikely scenarios of a) multiple HDMI VSDBs,
and b) HDMI VSDB 3D modes using VIC indexes that span across multiple
CTA VDBs, and the combination of the two.
