Ben Widawsky 999811572a intel_synth: Fix help message 
cyclonev has been a "supported" family since the initial commit. The old
commit message suggested to use a10gx which is incorrect.

Aside from the obvious lack of functional change due to this just being
a help message, users who were previously using "a10gx" for "cyclonev" will
also have no functional change by using "cyclonev" instead.
