[PATCH 07/11] time/alarmtimer:Convert to the new methods for k_clock structure

[Baolin Wang <baolin.wang@xxxxxxxxxx>]

This patch changes to the new methods with timespec64/itimerspec64
type of k_clock structure, and converts the timespec/itimerspec type to
timespec64/itimerspec64 typein alarmtimer.c file.
