ASoC: fsl_xcvr: Enable 2 * TX bit clock for spdif only case
The bit 10 in TX_DPTH_CTRL register controls the TX clock rate.
If this bit is set, TX datapath clock should be = 2* TX bit rate.
If this bit is not set, TX datapath clock should be 10* TX bit rate.
As the spdif only case, we always use 2 * TX bit clock, so
this bit need to be set.
