ARM: dts: msm: Reduce the proxy vote timeout for venus on msm8996

The PIL driver removes its proxy votes for the clocks and video
gdsc after 5 secs. Venus though, can go to power collapse 2
secs after it has been brought out of reset.
If Venus tries to go to power collapse between 2 secs and 5 secs,
this proxy vote from the PIL driver prevents gdsc regulator
shutdown. Hence, reduce the proxy timeout to 100 msecs instead.
