I assume this is for 3.10 now. Can you rework this to remove
bcm_timer_ids[] and that of_find_matching_node() call, and replace it
with e.g.:

CLOCKSOURCE_OF_DECLARE(kona, "bcm,kona-timer", kona_timer_init);

You'd need to change the prototype of kona_timer_init() to accept the DT
node pointer, and pass this through to kona_timers_init().

This would remove the need to have board_bcm.c call the custom
kona_timer_init(); it could use the new standardized clocksource_of_init
instead.
