arm64: dts: msm8996: fix PSCI entry-latency-us
The current entry-latency-us is too short.
The proper way to convert between the device tree properties
from the vendor tree to the upstream PSCI device tree properties is:
entry-latency-us = qcom,time-overhead - qcom,latency-us
which gives
entry-latency-us = 210 - 80 = 130
