This adds a relatively simplistic clock framework for sh. The initial goal behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU subtype-specific frequency setting and calculation code moved somewhere more sensible. This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.
