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.

This dates from commit db2a416556af0 in 2006 :-)
what was specifically excluded is the information on rates and channels.
Liam, any memories if this was intentional?
