[PATCHv2 1/2] CONFIG_SYS_NONCACHED_MEMORY: Move prototypes to include/cpu_func.h for consistency

Currently, a number of generic cache related functions have their common
prototype declared in include/cpu_func.h. Move the current set of
noncached functions there as well to match.

Changes in v2:
- New patch because of build failures noticed on v1.
