FPGA模拟SENSOR，MIPI CSI-2发送图像到RV1126
1：FPGA模拟Sensor， 使用MIPI CSI-2 Transmit，发送图像到RV1126。
2：MIPI CSI-2信号LANE，共5对。图像分辨率1920*1080，格式YUV422 8Bit，RGB565等。
3：调试
3.1：命令：v4l2-ctl -d /dev/video0 —set-fmt-video=width=1920,height=1080,pixelformat=UYVY —stream-mmap=3 —stream-skip=5 —stream-to=/tmp/cif2.out —stream-count=50 —stream-poll
3.2：log
