Currently the registration of critical clocks is done in the function shared between rk3066 and rk3188 clock trees. That results in them getting handled maybe before all of them are registered. Therefore move the critical clock handling down to the end of the soc- specific clock registration function, so that all clocks are registered before they're maybe handled as critical clock.

--- It looks like with the recent flexibilization of the gpio clocks in the pinctrl driver, we're shaking out some oddities from the clock trees.
