samus: support sensor at different power state.
Design Goals:
1. Every time the AP boots, the same default sensor settings are configured.
2. If the AP goes to suspend (S3) and wakes back up (S0),
then the AP sensor settings will be restored.
3. In S3 and in S5, only sample specific sensors that are needed.
BUG=chrome-os-partner:32368
BRANCH=ToT
TEST=Verified on Samus.
Verified suspend and resume logic with EC console messages.
- Test Case0: close lid & open lid
- Test Case1: powerd_dbus_suspend
