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.

Ben Widawsky 809b94a67b intel_synth: Make family explicit and match 
The help and code default to MAX10 for the family, however the couple of
if ladders defaulted to cycloneive. Fix this inconsistency and the next
patch will clean it up.
