mb/google/hatch: Change baseboard EC wake & SCI masks to match kohaku
1) Allows MKBP events from the EC to wake the system from suspend states. 2) Remove EC_HOST_EVENT_MKBP from the EC_SCI_EVENTS mask, so that MKBP events don't generate an SCI. The EC is also being changed to use host events to wake up the system, and use the EC_INT_L line for MKBP IRQ signalling. Otherwise, there would be two IRQs generated for MKBP events.
