According to the datasheet:
Digital Audio Interface Format (07h) register:
BIT6: Master/slave mode
0: Slave
1: Master
Current code sets TLV320AIC23_MS_MASTER bit for master mode,
but does not clear it 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

Current code sets BIT_CLK_MASTER and WORD_CLK_MASTER bits for master mode,
but does not clear these bits for slave mode.

This is not entirely true - there is this fussy '& 0x3f' operation that
does clear those bits a few code lines above your change. Now we can rid
of it thanks to your patch, hopefully for iface_breg too (in case if you
are going to send an another patch as this is applied) :-)
