[PATCH 10/24] timekeeping: Define a struct type for tk_core to make it reusable

The struct tk_core uses is not reusable. As long as there is only a single
timekeeper, this is not a problem. But when the timekeeper infrastructure
will be reused for per ptp clock timekeepers, an explicit struct type is
required.

Define struct tk_data as explicit struct type for tk_core.
