equiv_simple: Take FFs into account for driver map #4224

Closed povik closed 7 months ago

povik commented 7 months ago

This fixes an issue introduced in commit 26644ea due to which flip-flops are inadvertently ignored when building up driver map. The mentioned commit wasn't without functional change after all.

Thanks to @ArkadyKlimov who pointed this out.
