Dan Ravensloft 67b4ce06e0 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.
