arm64: dts: qcom: sdm845: correct dynamic power coefficients

Following sm8150/sm8250 update sdm845 capacity-dmips-mhz and
dynamic-power-coefficient based on the measurements [1], [2].

The energy model dynamic-power-coefficient values were calculated with
    DPC = µW / MHz / V^2
for each OPP, and averaged across all OPPs within each cluster for the
final coefficient. Voltages were obtained from the qcom-cpufreq-hw
driver that reads voltages from the OSM LUT programmed into the SoC.

Normalized DMIPS/MHz capacity scale values for each CPU were calculated
from CoreMarks/MHz (CoreMark iterations per second per MHz), which
serves the same purpose. For each CPU, the final capacity-dmips-mhz
value is the C/MHz value of its maximum frequency normalized to
SCHED_CAPACITY_SCALE (1024) for the fastest CPU in the system.

For more details on measurement process see the commit message for the
commit 6aabed55 ("arm64: dts: qcom: sm8250: Add CPU capacities and
energy model").
