samus: Make codec interrupt active high

Browse source 
The codec interrupt needs to be active high because multiple
interrupt sources share this line:

1) Headphone plug detect
2) Mic present
3) Hotword detect

These interrupt sources are OR-ed together.

BUG=chrome-os-partner:29649
BRANCH=samus
TEST=Jack detection works on samus
