ARM: dts: msm: update LPM parameters for 8x10v1 and v2

Platform PM driver takes LPM parameters as one of the input
and decide the best idle system low power mode. Current LPM
parameters are not optimal and this can lead to more power
consumption for APPS proc active usecases. This change tunes
the low power mode parameters such as "latency",
"time overhead", "steady state power" and "energy overhead"
for 8x10v1 and 8x10v2.
