mainboard/google/reef: Set edge triggered interrupt for GPIO_22
EC sets the logic level based on outstanding wake events. When GPIO_22
is configured as a level triggered interrupt, the events are not
cleared from the interrupt handler. Hence, we'd just be re-signalling
over and over causing an interrupt storm upon lid open. So, GPIO_22
needs to be configured as EDGE_SINGLE instead of LEVEL.
BUG=chrome-os-partner:62458
TEST=Lid close/open. check CPU usage using top. It should
not show 70% CPU usage.
