As I mentioned previously we might be able to convert the rockchip,rk2928-gate-clk stuff over to the generic gate-clock binding once hiword-mask support and support for clock-cells == 1 is added in. I'm hacking on the former now and the latter may go in for 3.12.

This adds a basic clock setup for rk3066a SoCs. Only the gates are set up currently, as the mux and dividers should use the upcoming generic devicetree bindings. Clocks whose rates need to be known are supplied by fixed-rate "dummy"-clocks that provide the correct rate. This is uncritical insofar that the only bootloader currently in existence for Rockchip devices is the propietary Rockchip one that always setups the clocks in the necessary way.
