davinci: dm646x: Add support for 3.x silicon revision

commit f63dd12da29f47c37bbc093abec098538e04357c upstream.

DM6467 silicon revisions 3.x have variant field in JTAGID register as '1'.
This path adds entry for the same in dm646x_ids to be able to boot on boards
with 3.x revision chips.

Also modifies name for 'variant=0' (revisions 1.0, 1.1).
