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 at 2011000 {
                         compatible = "syscon";
                         reg = <0x2011000 0x1000>;
                 };

yep, I will rename this in next version.

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

sounds good.

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?
