Alexandru M Stan 1d518fb85c motion_sense: Lower jitter of EC->AP timestamp
When the EC sends an interrupt to the AP notifying it of new
accelerometer data we need to make sure the spot we record the timestamp
of the event is virtually identical to the spot the AP records the same
point in time.

Therefore a better spot for that is right next to the gpio toggling of
the interrupt line.

BUG=b:67743747
TEST=In the kernel, fifo_info->info.timestamp still has sane values.
TEST=CTS should still pass
BRANCH=master
