This is actually a clock controller block that hw designers decided was
good place to shove the ipc bits (because there's room!). Can we call it

                l2cc: clock-controller@2011000 {
                        compatible = "syscon";
                        reg = <0x2011000 0x1000>;
                };

Eventually I'll add the specific krait compatible when we merge krait
clock support:

                l2cc: clock-controller@2011000 {
                        compatible = "qcom,kpss-gcc", "syscon";
                        reg = <0x2011000 0x1000>;
                        clock-output-names = "acpu_l2_aux";
                };

There are actually 3 ipc bits. I guess if we ever have to use the other
two we'll extend this binding to have the other bits specified some
other way?
