arm64: dts: qcom: qcs615: Add CPU and LLCC BWMON support

Add CPU and LLCC BWMON nodes and their corresponding opp tables to
support bandwidth monitoring on QCS615 SoC. This is necessary to enable
power management and optimize system performance from the perspective of
dynamically changing LLCC and DDR frequencies.
