 clock property

Hi Stephen,

The plan is for both the clock and reset will be under only the memory
region handle like
                sysctrl: system-controller@...01000 {
                        compatible = "syscon", "simple-mfd";
                        reg = <0x0 0xf0801000 0x0 0x1000>;

                        rstc: reset-controller {
                                compatible = "nuvoton,npcm845-reset";
                                reg = <0x0 0xf0801000 0x0 0xC4>;
                                #reset-cells = <2>;
                                nuvoton,sysgcr = <&gcr>;
                        };

                        clk: clock-controller {
                                compatible = "nuvoton,npcm845-clk";
                                #clock-cells = <1>;
                                clocks = <&refclk>;
                                clock-names = "refclk";
                        };
                };

is it problematic?

But this commit is not related to it.

Thanks,

Tomer
