Tell the base to hibernate when we are in S5, and no AC is connected.
Also, wake the base when AC status changes (S5), and when the system
transistions out of S5.
BRANCH=none
BUG=b:71874971
TEST=1. Lid EC console: apshutdown => Check that Base EC hibernates
2.a. Lid EC console: powerb; => Check that base reconnects
2.b. Connect/disconnect adapter: check that base disconnects
and reconnects
