xilinx: do not make DSP48E1 a whitebox for ABC9 by default (#2325) 
* xilinx: eliminate SCCs from DSP48E1 model

* xilinx: add SCC test for DSP48E1

* Update techlibs/xilinx/cells_sim.v

* xilinx: Gate DSP48E1 being a whitebox behind ALLOW_WHITEBOX_DSP48E1

Have a test that checks it works through ABC9 when enabled

Keith Rothman 819f1d8c20 Remove EXPLICIT_CARRY logic. 
The symbiflow-arch-defs tool chain no longer needs the EXPLICIT_CARRY
within yosys itself.
