arm64: dts: qcom: sm6350: Set up DDR & L3 scaling 



Add the CPU OPP tables including core frequency and L3 bus frequency.
The L3 throughput values were chosen by studying the frequencies
available in HW LUT and picking the highest one that's less than the
CPU frequency. DDR clock rates come from the vendor kernel.

Available values from the HW LUT:
300000000
556800000
652800000
806400000
844800000
940800000
1132800000
1209600000
1286400000
1401600000
1459200000
