ASoC: tegra: fix Tegra30 I2S capture parameter setup
commit c90c0d7a96e634a73ef1580f1d20993606545647 upstream. The Tegra30 I2S driver was writing the AHUB interface parameters to the playback path register rather than the capture path register. This caused the capture parameters not to be configured at all, so if capturing using non-HW-default parameters (e.g. 16-bit stereo rather than 8-bit mono) the audio would be corrupted. With this fixed, audio capture from an analog microphone works correctly on the Cardhu board.
