Provide a simple implementation of clk_set_parent() in the lantiq subarch so that callers of it will build without errors. Fixes these build errors: ERROR: modpost: "clk_set_parent" [sound/soc/jz4740/snd-soc-jz4740-i2s.ko] undefined! ERROR: modpost: "clk_set_parent" [sound/soc/atmel/snd-soc-atmel-i2s.ko] undefined!
