ASoC: wm8741: Fix setting interface format for DSP modes

commit 3a340104fad6ecbea5ad6792a2ea855f0507a6e0 upstream.

According to the datasheet:
Format Control (05h)
BITS[3:2]
        FMT[1:0] Audio data format selection
                00 = right justified mode
                01 = left justified mode
                10 = I2S mode
                11 = DSP mode
BIT[4]  LRP Polarity selec for LRCLK/DSP mode select
                0 = normal LRCLK poalrity/DSP mode A
                1 = inverted LRCLK poarity/DSP mode B

For SND_SOC_DAIFMT_DSP_A, we should set 0x000C instead of 0x0003.
For SND_SOC_DAIFMT_DSP_B, we should set 0x001C instead of 0x0013.
