[PATCH 09/11] ARM: dts: rk3188: add cru node and update device clocks to use it

Wed Apr 16 09:44:43 PDT 2014
This adds a node for the clock and reset unit on rk3188 SoCs and updates
the device nodes retrieve their clocks from there, instead of the previous
gate clock nodes.
As the clocks diverge a bit until rk3066 can catch up, the shared nodes
between rk3066 and rk3188 get separated clocks-properties in the rk3188.dtsi.
