This commit adds extra `extract_fa` Yosys pass combined with fa/ha techmapping. It runs only when user specifies $fa/$ha to DPK mapping. This commit also adds new `adder_mapping` attr to the `synthesize_rtl` rule. This file provides Yosys with $fa/$ha blackboxes. This change may affect existing designs, as extra `opt` pass is being run. Signed-off-by: Maciej Dudek <mdudek@antmicro.com>
