解决：

rknpu_devfreq.c:

static const struct rockchip_opp_data rk3576_npu_opp_data = {
    .set_read_margin = rk3576_npu_set_read_margin,
//     .set_soc_info = rockchip_opp_set_low_length, 未定义, 需要删除
#if KERNEL_VERSION(6, 1, 0) <= LINUX_VERSION_CODE
    .config_regulators = npu_opp_config_regulators,
    .config_clks = npu_opp_config_clks,
#endif
};
