I must say, there was a gap in my understanding of the comment.
So, here is the implementation change:

-> Call omap2_dm_timer_early_init(u8 gptimer_id) from omap2_gp_timer_init()
-> Initialize only gptimer_id inside this function
-> In the regular init skip initialization of gptimer_id

As a result of this, we can rid of double registration and related code.
