driver: bmi160: Fix for significant motion while in suspend.
- Add interrupt latching: notice that interrupt register
was cleared before entering the task irq handler.
Add a 5ms latching time address the issue.
Check it was not a problem for regular operation.
- Fix FIFO interrupt setting: interrupt when FIFO was full was
missing from one register
- Really disable FIFO when AP does not want data from sensors.
BRANCH=smaug
BUG=b:23570481
TEST=check that significant motion and double tap are reliable in S3.
