chromeec: Notify CREC device of wakeup events 

Whenever there is a new EC event that could be wake-capable, notify
CREC device of this using notification value 0x2 i.e. device
wake. This allows Linux kernel to track active_count value correctly
for CREC device.

BUG=b:69118395
BRANCH=None
TEST=Verified on Soraka:
1. Put device into suspend
2. Wake up using mode change/lid open
3. Check that the active_count for GOOG0004 has increased
(cat wakeup_sources | grep GOOG0004)
