drm/edid: parse Tiled Display Topology Data Block for DisplayID 2.0

Currently we only parse the Tiled Display Topology Data Block for
DisplayID structure version 1.2, but not 2.0. The contents seem to be
the same for both, so expand the parsing to structure version 2.0.

Note that DisplayID spec version is not the same as DisplayID structure
version; DisplayID 1.3 uses structure version 1.2, and DisplayID 2.0-2.1
use structure version 2.0. Lovely.
