One method would be to use an init call from <linux/init.h> which is called before these are done (you'll have to work out which one is suitable for yourself).
Either that or ensure that your boards always call a specific routine in their init sequence to ensure clocks are registered before the timer needs them.
If I remeber correctly, map_io() is actually called before the timers are initialised, so you could add your clocks there.
