While transitioning to having better clarity between the modules, it's desirable to have the function name prefixes reflect the module. Functions in intel_foo.c should be prefixed intel_foo_. Expose only one CDCLK init/uninit function from intel_cdclk.c instead of one per platform. Obviously this adds one "unnecessary" if ladder within the entry points. However it should be considered more of a CDCLK implementation detail how this is done per platform, instead of exposing the fact. In other words, abstract the CDCLK module better. No functional changes.
