Subject: [PATCH 4/5] drm/edid: convert drm_parse_vcdb to use struct cea_db *

Address the following
        FIXME: convert parsers to use struct cea_db
in the parser drm_parse_vcdb

cea_db contains len and then data. Appropriately change the indices
when referring to individual elements (db[n] becomes data[n-1]).
