Define bindings for the Qualcomm Krait CPU and L2 clock controller. This
device is used on old Qualcomm SoCs (APQ8064, MSM8960) and supports up
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.
