arm64: dts: qcom: sm8150: Add CPU opp tables

Add OPP tables to scale DDR and L3 with CPUs for SM8150 SoCs.
This gives a significant performance boost for cpu-ddr loads.
Below is the results for mbw benchmark with and without the opp tables.

/mbw 1500
		Without l3/ddr scaling		With l3 ddr/scaling
MEMCPY(MiB/s)		3574				10448
DUMB(MiB/s)		3500				11721
MCBLOCK(MiB/s)		8976				23595
