ASoC: Leave input audio data bit length settings untouched in wm8711_set_dai_fmt
Current implementation in wm8711_set_dai_fmt always clear BIT[3:2] (the Input Audio Data Bit Length Select) of WM8711_IFACE(07h) register. Input Audio Data Bit Length Select bits are set by wm8711_hw_params, we should leave BIT[3:2] untouched in wm8711_set_dai_fmt.
