eve: Enable gpio interrupt for bmi160 accelgyro sensor

The config option to use interrupts for this sensor was defined,
however, the gpio interrupt for the interrupt from this sensor was not
being enabled.

BUG=b:35584895
BRANCH=none
TEST=Added a wire to the interrupt line on an Eve. Verified that when
the interrupt was triggered (verified by scope) that ISR for this gpio
was being called.
