intel: Map M9K BRAM only on families that have it
...
This regresses Cyclone V and Cyclone 10 substantially, but these
numbers were artificial, targeting a BRAM that they did not contain.
Amusingly, synth_intel still does better when synthesizing PicoSoC
than Quartus when neither are inferring block RAM.

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.
