google/nocturne: Add MKBP events as a wake source.
We would like to wake nocturne up in suspend from an MKBP event. On Nocturne, MKBP events are notified to the host via a GPIO from the EC, EC_INT_L. However, the AP cannot wake from suspend from this GPIO. Therefore, we'll use the host event interface to wake the system instead.
This commit simply enables MKBP events to wake the system in suspend.
BUG=chromium:786721 BRANCH=firmware-nocturne-10984.B TEST=Build and flash nocturne, generate MKBP events on the EC and verify that the system wakes up in suspend.
