The DSL-2740B/DSL-2741B rev C2 support was missing the board definition,
resulting in a kernel panic on boot.
This patch adds it, and also renames the generated image name to properly
reflect that it is for the revision C2, and for both the DSL-2740B and
DSL-2741B.

Port the mechanism for different default configurations from ar71xx and
use the old configuration as the default configuration. This should have
no functional differences to before.
While we are at it, remove the obsolete nat option.
