[PATCH] ASoC: wm_adsp: mark more data structures with the const qualifier

[Simon Trimmer]

The callback structures and memory region type table can be marked as
const as they will not change during use.

Fix checkpatch warning against wm_adsp_find_region function by moving
const keyword to form the 'static const struct' pattern.
