[PATCH v2 6/6] kirkwood: implement compatibility version for DSA migration

[Adrian Schmutzler]

This implements the newly introduced compat-version to prevent
upgrade between swconfig and DSA for kirkwood.

Just define a compat version with minor increment and an appropriate
message for both image (in Makefile) and device (in base-files).

Since we never removed SUPPORTED_DEVICES for this target, we don't
have to add it back either.
