clk: rockchip: fix section mismatches with new child-clocks To model the muxes downstream of fractional dividers we introduced the child property, allowing to describe a direct child clock. The first implementation seems to cause section warnings, as the core clock-tree is marked as initdata while the data pointed to from the child element is not. While there may be some way to also set that missing property in the inline notation I didn't find it, so to actually fix the issue for now move the sub-definitions into separate declarations that can have their own __initdata properties.
