This patch introduces the new methods with timespec64 type for k_clcok structure, converts the timepsec type to timespec64 type in k_clock structure and converts the itimerspec type to itimerspec64 type to ready for 2038 issue.
Next step will migrate all the k_clock users to use the new methods with timespec64 type and itimerspec64 type, and it contains the files of posix-timers.c, mmtimer.c, alarmtimer.c, posix-clock.c and posix-cpu-timers.c.
