ASoC: fsl_spdif: Use clk_set_rate() for spdif root clock only
The clock mux for the Freescale S/PDIF controller has eight clock sources while most of them are from other moudles and even system clocks that do not allow a rate-changing operation. So we here only allow the clk_set_rate() and clk_round_rate() happened to spdif root clock, the private clock for S/PDIF controller.
