This commit moves the Orion5x platforms using the Device Tree to use the recently introduced clock driver for Orion5x. To achieve that, it: * Adds the necessary DT description of the clock. * Selects ORION_CLK to enable the compilation of the clock driver. * Call of_clk_init() instead of the Orion5x-specific clock initialization function.
