octopus: convert boards to use hardware int

Recent kernel changes expect the EC to use a dedicated interrupt pin
from the EC to the AP to notify the AP of pending sensor data (instead
of using an eSPI "interrupt").

The octopus boards have this hardware support, we just need to enable
the EC use it.

BRANCH=octopus
BUG=b:122552125,b:120679547
TEST=perform sensor tests on various octopus boards
