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.
