clk-fixed-rate currently names clocks according to a node's name without
the unit address. When faced with the legal and technically correct DT
structure below, this causes rgistration attempts for 3 clocks with the
same name, 2 of which fail.

	clocks {
		compatible = "simple-bus";
		#address-cells = <1>;
		#size-cells = <0>;

		clk_mmc: clock at 0 {
			compatible = "fixed-clock";
			reg = <0>;
...
		clk_i2c: clock at 1 {
			compatible = "fixed-clock";
			reg = <1>;
...
		clk_spi: clock at 2 {
			compatible = "fixed-clock";
			reg = <2>;
...

I'd argue that this case isn't valid.

The fixed-clock binding doesn't define a reg, yet simple bus binding
implies that the reg property of child nodes should be interpretted as
the same address space as their parent (MMIO in this case?). The
fixed-clock nodes reg proeprties clearly aren't MMIO addresses.

Additionally, the _requred_ ranges property is missing.

Oh, IIRC that was deliberate to indicate that the child address space
was disjoint from the parent address space.
