ARM: dts: msm: Update LPM parameter values for msm8909

PM driver takes LPM parameters as one of the input
and decides the best low power mode. Current LPM
parameter values are not optimal and this may lead
to more power consumption for APPS proc active
usecases.

Tune the low power mode parameter values such as
"latency","time overhead","steady state power"
and "energy overhead".
