Patch looks good in general. However this is a good opportunity to stop
the madness around the registration functions in these basic clock
types.

clk_register is really all that we need since we've had struct
clk_init_data for a while. Initializing a multiplier should be as simple
as:

	struct clk_multiplier clk_foo = {
		.hw.init = &(struct clk_init_data){
			.name = "foo",
			.parent_names = (const char *[]){
				"bar",
			},
			.num_parents = 1;
			.ops = &clk_multiplier_ops,
		},
		.reg = 0xd34db33f,
		.shift = 1,
		.width = 2,
	};

	clk_register(dev, &clk_foo.hw);

This is nice since it turns these basic clocks into even more of a
library and less of a poor mans driver.

(I really hope the above works. I did not test it)

Is it possible you can convert to using this method, and if it is
correct for you then just remove clk_multiplier_register altogether? (In
fact you might not use the registration function at all since you use
the composite clock...)
