mainboard/google/kahlee: Enable EC wake on GPIO24
The grunt EC uses GPIO24 (EC_PCH_WAKE_L) to signal wake-up events to the AP.
On Stoney, GPIO24 maps to GEVENT (GPE) 15.
The kahlee EC uses GPIO2 (EC_PCH_WAKE_L) to signal wake-up events to the AP.
On Stoney, GPIO2 maps to GEVENT (GPE) 8.
BUG=b:78461678
TEST=powerd_dbus_suspend, tap any key on keyboard wakes from S3.
TEST=sign in, EC: lidclose, EC: lidopen => system wakes from S3.
