Subject: [PATCH] arm64: dts: qcom: sc8280xp: Fill in EAS properties
Replace the bogus capacity-dmips-mhz values and add the measured
dynamic-power-coefficient values.
The power numbers were measured by matters much more precise than the
laggy and cache-y pmic_glink battery data, though the reported values
were only accurate to 10mA. But that shouldn't be an issue, especially
for the fat and power-hungry X1Cs and given that *each SoC unit* has
somewhat different frequency-voltage maps.
