after days of ad9361 noise analysis with multiple borad, it turns out that the ad9361 RxFir can significantly reduce max noise level, with which the interference-to-noise ratio can be greatlt improved, and the nulling algotirhm can finally work properly; another experiment is about duifei multi rx channel phase-amplitude consistence, for which the rx external lo of ad9361 is enabled, but extra phase compensation is needed because the trace length of external lo is not matched
in duifei_basic_v1.0, ila of tx and rx signal is seperated into two ilas; in module ad9361_mapping, the DDR_CLK_MODE of rx mapping iddr is changed to SAME_EDGE, and the output iq of iddr is swappedto satisfy ad9361 data interface
delete redundant file in dl814_k7_basic; simply duifei_cmos to duifei_basic and archive the project; rename duifei_cmos to duifei_cal_coarse and add ad9361 multichip calibration function, but not tested
