dt-bindings: clock: qcom,msm8996-cbf: Describe the MSM8996 CBF clock controller 



MSM8996 Core Bus Fabric (CBF) clock controller clocks an interconnect
between two CPU clusters. The CBF clock should follow the CPU
frequencies to provide enough bandwidth between clusters. Thus a single
driver implements both a clock and an interconnect to set the clock
rate.
