OMAP: clockdomain: Infrastructure to put arch specific code

Put infrastructure in place, so arch specific func pointers
can be hooked up to the platform-independent part of the
framework.
This is in preparation of splitting the clockdomain framework into
platform-independent part (for all omaps) and platform-specific
parts.
