x86: use charge state hook to wake up power button task
This is cleaner than having the charge state machine explicitly know
about the power button task.
BUG=chrome-os-partner:21610
BRANCH=none
TEST=reboot EC; see that power button task does not leave init-on state until
just after the charge state initializes:
[0.022646 Charge state init -> idle0 after 0.005908 sec]
[0.022956 PB task 8 = init-on]
[0.023147 PB PCH pwrbtn=LOW]
[0.023303 PB task 6 = released, wait 199996]
