The MIPS BMC63XX subarch does not provide/support clk_set_parent(). This causes build errors in a few drivers, so add a simple implementation of that function 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!
