ASoC: davinci-mcasp: Fix TDM slot rx/tx mask associations
Fixes the associations between the tx_mask and rx_mask and the associated playback / capture streams during setting of the TDM slot. With this patch in place it is now possible for example to only populate tx_mask (leaving rx_mask as 0) for output-only codecs to control the TDM slot(s) the McASP serial port uses for transmit. Before that, this scenario would incorrectly rely on the rx_mask for this.
