Clocks registration cannot be done in early init callback (as formerly done by the old clk implementation) because it requires dynamic allocation which is not ready yet during early init. In the other hand, at91 clocks must be registered before at91sam926x_pit_init is called because PIT (Periodic Interval Timer) driver request the master clk (mck). A new function (at91sam9_dt_timer_init) is created to fullfil these needs. This function registers all at91 clks using the dt definition before calling the PIT init function. The device tree clock registration is enabled only if common clk is selected. Else the old clk registration is been done during at91_dt_initialize call.
