[WATCHDOG] timers cleanup
- Use timer macros to set function and data members and to modify
expiration time.
- Use DEFINE_TIMER for single (platform dependent) watchdog timers and
do not init them at run-time in these cases.
- del_timer_sync is common in most cases -- we want to wait for timer
function if it's still running.
