ASoC: Constify channel mapping array arguments in set_channel_map()
There is no need for implementations of DAI set_channel_map() to modify
contents of passed arrays with actual channel mapping. Additionally,
the caller keeps full ownership of the array.
Constify these pointer arguments so the code will be safer and easier to
read (documenting the caller's ownership).
