ASoC: tlv320aic3x: Clear BIT_CLK_MASTER and WORD_CLK_MASTER bits for for slave mode
According to the datasheet:
Page0 / Register8: Audio Serial Data interface Control Register A
BIT 7: Bit Clock Directional Control
0: Bit clock is an input (slave mode)
1: Bit clock is an output (master mode)
BIT 6: Word Clock Directional Control
0: Word clock is an input (slave mode)
1: Word clock is an output (master mode)
Current code sets BIT_CLK_MASTER and WORD_CLK_MASTER bits for master mode,
but does not clear these bits for slave mode.
