Move atmel_tc_divisors and atmel_tcb_dt_ids definitions to the header file
so they can be used without using tclib.

Why not kill those structure and use the TIMER_OF_DECLARE with the
corresponding probe function which will initialize to 16 or 32 counter
width?

I'm dropping this patch and the structures but doing the differentiation
with TIMER_OF_DECLARE is not possible as this has to match
"atmel,tcb-timer" and the differentiation is done on the parent
compatible.
