For the case we met in patch 2, it is not related with trigger things.
We just set some series of tuples including brightness and duration
(ms) to the hardware to enable the breath mode of the LED, we did not
trigger anything. So it is weird to write something to trigger file to
deactive the pattern.

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.

This patch splits out the guts of the syscall and changes the syscall
implementation to prepare the converting to 64bit methods for the syscall
function in posix-timers.c file. And next patch will convert the syscall
to 64bit methods with timespec64/itimerspec64 type.

This patch converts to the 64bit methods with timespec64/itimerspec64 type
for the syscall function, and changes the syscall implementation according to
the CONFIG_64BIT macro.
Also introduces some default functions with timespec64/itimerspec64 type
for the 64bit methods.

This patch introduces the do_sys_settimeofday64() function with timespec64
type, that makes this function ready for 2038 issue when setting the time of
day.
And moves the do_sys_settimeofday() function to the timekeeping.h file.
