Define bindings for the Qualcomm Krait CPU and L2 clock controller. This

to 4 core clocks and a separate L2 clock. Furthermore, L2 clock is
represented as the interconnect to facilitate L2 frequency scaling
together with scaling the CPU frequencies.

Worth noting that there's no Krait cluster containing more than 4
cores and the last SoC using this uarch was released 10y ago, so
we can quite confidently say that the max cpu no won't change.
Yep. It it were new bindings, I'd probably use a different order: L2,
then CPUs. But here I'm just documenting what is already done by the driver.
