ASoC: Intel: byt-rt5640: Remove IN2N pin from DAPM route table 



I tested couple byt-rt5640 based platforms and they have single-ended
headset microphone connection to IN2P only. I guess IN2N was either defined
by accident or some early platform had floating ground for headset. It's
better to remove IN2N and add a custom route for such a platform if needed.
