i2c-msm-v2: decrease runtime pm time to 250msec

Browse source 
Runtime-pm autosuspend delay is set to 1 second. This
long period is used to avoid thrashing due to long time
it takes for bus-pm voting. The period is reduced to a
quarter to optimize power. This number is tested for
trade-off between power and performance.
