This allows us to move the overlapping devicetree clocks to be children of the related clksel nodes. And then we need the reg property only for the parent clksel node. We want to set #clock-cells = <1> in case we ever start parsing the clkcsel clocks directly using a clksel driver rather than using the existing component clock drivers and child nodes. We also need to update the clock drivers to get the IO address from the parent clksel node before updating the dts files. These will be posted as separate patches.
