Subject: [PATCH 2/2] arm64: dts: qcom: msm8996: Add support for the CBF clock

Add the CBF PLL register to the kryocc node and assign a frequency
to the clock.

This makes sure the core cluster interconnect is running at a decent
speed, so that it's no longer a pain to use the device with all cores
enabled.
