drivers: Update timer APIs for Linux v6.15

Browse Source 
In Linux v6.15, the timer APIs hrtimer_init() and del_timer() have been
removed. The hrtimer_setup() was added in Linux v6.13 to replace
hrtimer_init() and hrtimer_init() have finally been removed. The
functions del_timer()/del_timer_sync() were renamed to
timer_delete()/timer_delete_sync() in Linux v6.15. Use conftest to
detect these changes and update the drivers as necessary.
