arm64: dts: qcom: sm8650: update the cpus capacity-dmips-mhz

Browse Source 
After some more advanced benchmarks with Integer, Floaring Point,
Encryption, Compression, NEON, ... on the A520, A720 and X4 cpus,
the median gain with the same frequency range is:
- 281% of A720 over A520
- 126% of X4 over A720

When adjusted with the frequency delta, we get better values
describing the difference in capacity, showing the weakness of
the A520 designed for very small tasks while the A720 and X4
are much more powerful.
