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.
