isl923x: Set OTG enable debounce time to 150ms
The default setting is to wait 1.3s from receiving the command, to
enable the OTG output: that's too long, and makes time to active
base very long when running on battery.
BRANCH=none
BUG=b:76396020
TEST=Probe POGO 1/5 and one of the USB lines, check that time from
connect to active USB is reduced to 580 ms (from 1920 ms).
