arm64: dts: rockchip: add clocks property to cru node rk3308

Add clocks and clock-names to the rk3308 cru node, because
the device has to have at least one input clock.
Also in case someone wants to add properties that start with
assign-xxx to fix warnings like:
'clocks' is a dependency of 'assigned-clocks'
With the addition of new properties also sort the node properties
a little bit.
