ASoC: fsl_sai: Drop unnecessary defines

The fsl_sai driver has FSL_FMT_TRANSMITTER and FSL_FMT_RECEIVER defines
which are used in a single function only then are then only translated
into a bool 'tx' variable. Drop the defines and pass the boolean value
directly to fsl_sai_set_dai_sysclk_tr(). No functional change.
