nocturne: Restart base detection in S3.
nocturne: Restart base detection in S3.

Previously, the base detection state machine was restarting in S5,
however if the state machine ran through its loop and the system had not
transitioned to S3 yet, the state machine may have been disabled.

This commit simply changes the point which the state machine is
restarted from S5 to S3.  Since it's active in S3 and higher, we should
avoid that case of having the state machine being disabled when the
system is up.

BUG=b:111417839, b:111540121
BRANCH=none
TEST=shut device down, attach base, boot to S0, verify that base is
always detected.
