ASoC: tlv320aic3x: Clear BIT_CLK_MASTER and WORD_CLK_MASTER bits for for slave mode

Browse source 
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.
