When using fpga to carry out difftest, difftest will read out the architecture related information from the dma interface as a host program, and check the register on the PC side. usage make fpga-build，./fpga-host --diff=nemu.so

The idea of this function comes from the revision of encore. Thanks to the support of Teacher Shi Kan and Xu Shuoxiang for providing the XDMA initialization code (f7f0f8b), and Zhang Shoulin for helping debug the FPGA
