posix-cpu-timers: Replace cpu_timer_pid_type with clock_pid_type
Taking a clock and returning a pid_type is a more general and a superset of taking a timer and returning a pid_type. Perform this generalization so that future changes may use this code on clocks as well as timers. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com>
