ARM: dts: ci4x10: Adapt to changes in imx6qdl.dtsi regarding fec clocks

Commit f3e7dae3 ("ARM: dts: imx6qdl: add enet_out clk
support") added another item to the list of clocks for the fec
device. As imx6dl-eckelmann-ci4x10.dts only overwrites clocks,
but not clock-names this resulted in an inconsistency with
clocks having one item more than clock-names.

Also overwrite clock-names with the same value as in
imx6qdl.dtsi. This is a no-op today, but prevents similar
inconsistencies if the soc file will be changed in a similar way
in the future.
