The rxtx2 clock of i.MX6 S/PDIF is currently set to "asrc" clock. However, according to SoC documentation, rxtx2 is connected to ASRC_EXT_CLK, a different external clock.
Testing on Cubox-i system seems to confirm that: when fsl_spdif is forced to select rxtx2 as input clock, audio playback fails with an I/O error.
Set rxtx2 to the dummy clock by default to prevent fsl_spdif from selecting it.

Acked, thank you!
P.S. We might also revive rxtx5 (SYSCLK) since the driver now has the capability to derive clock from it.
This one seems clear enough.
