mb/google/hatch: Modify kohaku's EC_SCI_EVENTS mask 

Remove EC_HOST_EVENT_MKBP from kohaku's 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.

BUG=b:144122000
BRANCH=firmware-hatch-12672.B
TEST=System shows ACPI interrupt as the wakeup IRQ, and the
MKBP host event is properly processed as well.
