wifi-加载驱动

IWifi.hal 驱动加载和函数映射（HIDL）

WifiService(java进程)通过IWifi.hal HIDL接口调用到C++端的Wifi.cpp

 驱动加载时序

驱动加载代码流程：

Wifi.cpp-start->startInternal

WifiStatus Wifi::startInternal() {
    if (run_state_ == RunState::STARTED) {
        return createWifiStatus(WifiStatusCode::SUCCESS);
    } else if (run_state_ == RunState::STOPPING) {
        return createWifiStatus(WifiStatusCode::ERROR_NOT_AVAILABLE,
                                "HAL is stopping");
    }

//初始化WifiModeController和LegacyHal
    WifiStatus wifi_status = initializeModeControllerAndLegacyHal();
    if (wifi_status.code == WifiStatusCode::SUCCESS) {
        // Create the chip instance once the HAL is started.
        chip_ = new WifiChip(kChipId, legacy_hal_, mode_controller_,
                             feature_flags_);
        run_st
