Ruibin Chang 4ce0ff5ef4 drivers/timer/it8xxx2: fix busy wait timer race condition 
Command "waitms 50" on ChromeBook EC console, then it will crash EC.

Because arch_busy_wait() is re-entried by two different tasks,
the second calling will reset the timer and may cause the first
calling to fail to reach the waiting destination
(if the first calling's wait time is longer enough).

Verified by follow test pattern:
west build -p auto -b it8xxx2_evb tests/kernel/timer/timer_api
west build -p auto -b it8xxx2_evb tests/kernel/timer/timer_error_case
west build -p auto -b it8xxx2_evb tests/kernel/timer/timer_monotonic
west build -p auto -b it8xxx2_evb tests/kernel/timer/starve
west build -p auto -b it8xxx2_evb tests/kernel/context
