ASoC: fsi: remove platform depended .set_rate() callback support

ab6f6d85210c4d0265cf48e9958c04e08595055a
(ASoC: fsi: add master clock control functions)
added driver level clock control functions.
And now, platform depended .set_rate() is no longer needed.
This patch removed unnecessary .set_rate() platform callback support.
