[PATCH 1/1] timecounter: Make cyclecounter struct part of timecounter struct

There is no real need for the users of timecounters to define cyclecounter and timecounter variables separately. Since timecounter will always be based on cyclecounter, have cyclecounter struct as member of timecounter struct. Suggested-by: Chris Wilson Signed-off-by: Sagar Arun Kamble Cc: John
