lm4: Increase time to wake up from deep sleep
The recent change to decrease the time to wake up from deep sleep when
not using LFIOSC was too agressive. Increase the time to wake up based
upon the worst observed case.
BUG=chrome-os-partner:35184
TEST=Manual on Samus. Go to deep sleep, verify that no "overslept by
Xus" prints are seen.
BRANCH=Samus
