Revert "power: Clear AP_IDLE when waking up by PB or LID"
This reverts commit 27ee378bb78a299a0983379be83eb6d55860b4ae.
Reason for revert: b/162508724
A wake-up source from hibernation needs to be determined only by RO. Reverting back to the original implementation: CL:2236589.
Original change's description:
> power: Clear AP_IDLE when waking up by PB or LID
>
> Currently, AP_IDLE is cleared when EC wakes up by the power button or
> the lid open.
>
> This patch extends the logic from CONFIG_EXTPOWER_GPIO to
> CONFIG_EXTPOWER so that the bug (chromium:1073960) can be also fixed
> on the boards using non-GPIO method for extpower_is_present.
>
> Tested as follows on Trembyle:
> 1. Put DUT in hibernation.
> 2. Wake up DUT and observe:
> a. When waking up by power button, AP is turned on.
> b. When waking up by lid open, AP is turned on.
> c. When waking up by AC, AP is left idle.
>
> BUG=b:157077589, chromium:1073960, b:159350276
> BRANCH=none
> TEST=See above.
