Separate FAFT tests to improve run time

The tests are capable to moving the DUT into the required state (dev
or normal), but frequent state change takes a lot of time. It is
better to run tests in series by the initial state (dev/control). The
EC tests are in their own category. This will also allow to run tests
concurrently on multiple DUTs.

There are a few tests which have 'faft' in the SUITE = section, but
are not classified as either dev, normal or ec - they will be assigned
to one of the categories in a separate change.
