ARM: dts: rockchip: move edp assigned-clocks to edp node on rk3288

The rk3288 power-controller node contains an assigned-clocks property
that conflicts with the bindings. From the git history it shows that they
wanted to assign the rk3288 EDP_24M clock input centrally before an edp
node was available. Move the edp assigned-clocks property to the edp node
to reduce dtbs_check output.
