msm: ipa: reduce sps power management timeout to 100 msec

Currently, SPS driver holds IPA clocks for 1000 msec after IPA clocks are
no longer required. This is done in order to prevent frequent toggling of
IPA clocks. This long timeout may degrade power performance. Reducing the
tieout to 100 msec.
