From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

snd_soc_set_runtime_hwparams() is called from each driver
to initialize hw parameters,
but coping each parameters one-by-one.

Current code is not copying all parameters, but no big effect
if we do it. This patch copies all parameters by simple code.
