Moved, renamed, and deleted files
The original directory structure was scattered and unorganized. Changes are basically to make it look like kernel structure.

- * driver by calling these functions.

- * @clock_adjtime: Adjust the clock
- * @clock_gettime: Read the current time
- * @clock_getres: Get the clock resolution
- * @clock_settime: Set the current time value
- * @timer_create: Create a new timer
- * @timer_delete: Remove a previously created timer
- * @timer_gettime: Get remaining time and interval of a timer
- * @timer_settime: Set a timer's initial expiration and interval
