Add patch for realtek codec in Lenovo B50-70 that fixes inverted internal microphone channel. Device IdeaPad Y410P has the same PCI SSID as Lenovo B50-70, but first one is about fix the noise and it didn't seem help in a later kernel version. So I replaced IdeaPad Y410P device description with B50-70 and apply inverted microphone fix.
