History
Jason e5d1b3cfc3 Gap 4 USB Read Path: wire host-to-FPGA command path with toggle CDC, add read path tests 
- usb_data_interface.v: Add FT601 read FSM (RD_IDLE/OE_ASSERT/READING/
  DEASSERT/PROCESS) + cmd_data/valid/opcode/addr/value output ports
- radar_system_top.v: Connect cmd_* ports from usb_inst, add toggle CDC
  for cmd_valid (ft601_clk -> clk_100m), add command decode registers
  (mode/trigger/cfar_threshold/stream_control), wire host_mode and
  host_trigger to rx_inst
- radar_receiver_final.v: Add host_mode[1:0] and host_trigger input
  ports, replace hardcoded mode/trigger in radar_mode_controller instance
- tb_usb_data_interface.v: Connect cmd_* ports, add host data bus driver,
  add Test Groups 12 (single command), 13 (multiple commands), 14
  (read/write interleave). USB TB now has 55 checks.

Regression: 18/18 PASS
