[PATCH 06/27] dm: test: Add support for new sequence numbers

[Simon Glass]

Tests need to rebuild the driver model data structures to avoid being
affected by the operation of an earlier test. Do the same for the new
bind-time sequence numbers.

Also add a test that the new sequence numbers work as expected. Every
device should get one.
