OK so then I suggest updating the description with something
like "With __omap_sync32k_timer_init() now taking the clock
source as a parameter, we no longer need __omap_gptimer_init().
Note that __omap_sync32k_timer_init() gets renamed in the
later patches as it's no longer 32k source specific".

Tony
