rockchip: clk: rk3399: handle clk_enable requests for USB3
The "simple" OF glue layer for the Designware USB3 core enables all refernced clocks. These need to be need to be implemented otherwise the driver fails to probe. A dummy implementation that simply returns success is sufficient since the RK3399 comes out of reset with all clock gates open.
