Fixes 78/xiaozhi-esp32#350

[78]

区别是什么？把一路输入的修改，变成全部输入的修改？

哦，我才发现原本注释掉的那一行是单路调整增益对吧： // ESP_ERROR_CHECK(esp_codec_dev_set_in_channel_gain(input_dev_, ESP_CODEC_DEV_MAKE_CHANNEL_MASK(0), 40.0)); 我去掉注释测试过，启动有报错： `I (733) I2S_IF: channel mode 2 bits:16/16 channel:4 mask:3 I (743) I2S_IF: TDM Mode 0 bits:16/16 channel:4 sample_rate:24000 mask:3 I (753) I2S_IF: channel mode 0 bits:16/16 channel:4 mask:3 I (753) I2S_IF: STD Mode 1 bits:32/32 channel:4 sample_rate:24000 mask:0 I (763) Adev_Codec: Open codec device OK ESP_ERROR_CHECK failed: esp_err_t 0x106 (ESP_ERR_NOT_SUPPORTED) at 0x4201c06a --- 0x4201c06a: K10AudioCodec::EnableInput(bool) at /Users/nbzx/Developer/esp32/xiaozhi-esp32/main/boards/df-k10/k10_audio_codec.cc:179 (discriminator 2)

esp_codec_dev_set_in_channel_gain

如果取消注释，就不能正常跑了。

亲测esp-box-lite中也有用，麻烦在合pr时，也把esp-box-lite也给应用下。。

验证了一下，可行。

ES7210：

    codec->base.set_mic_gain = es7210_set_gain;
    codec->base.set_mic_channel_gain = es7210_set_channel_gain;

ES7243E:

codec->base.set_mic_gain = es7243e_set_gain;

除了ES7210有set_mic_channel_gain，其他的如ES7243E都只有set_mic_gain。 所以这个地方的增益，应该用esp_codec_dev_set_in_gain()。
