[PATCH 2/3] clk: Forward declare struct of_device_id in linux/clk.h

[Andrey Smirnov]

Forward declare struct of_device_id in linux/clk.h in order to avoid
warnings like the following:

warning: 'struct of_device_id' declared inside parameter list will not be visible outside
of this definition or declaration
 int of_clk_init(struct device_node *root, const struct of_device_id *matches);
                                                        ^~~~~~~~~~~~
