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.
