hw/misc: Introduce the Xilinx CFI interface

Browse Source 
Introduce the Xilinx Configuration Frame Interface (CFI) for transmitting
CFI data packets between the Xilinx Configuration Frame Unit models
(CFU_APB, CFU_FDRO and CFU_SFR), the Xilinx CFRAME controller (CFRAME_REG)
and the Xilinx CFRAME broadcast controller (CFRAME_BCAST_REG) models (when
emulating bitstream programming and readback).
