alarmtimer: Switch to use hrtimer_setup() and hrtimer_setup_on_stack()

Browse Source 
hrtimer_setup() and hrtimer_setup_on_stack() take the callback function
pointer as argument and initialize the timer completely.

Replace the hrtimer_init*() variants and the open coded initialization of
hrtimer::function with the new setup mechanism.

Switch to use the new functions.
