Keyboard: Add AP wakeup to PS2 trackpoint interrupt
Wake up AP for PS2 interrupt using Device Event as trigger. AP
must have device event wakeup mask enabled and board must select
CONFIG_DEVICE_EVENT in EC.
This device event is only triggered when the chipset is suspended to
avoid triggering SCIs in S0.
BUG=b:160345665
BRANCH=Zork
TEST=Wake from S3 by trackpoint
