driver: bmi160: Add FIFO and interrupt support
Add FIFO support, where bmi160 hardware FIFO is copied in local fifo.
Add rudimentary support for single/double tap and lift detection.
BUG=chrome-os-partner:39900
BRANCH=smaug
TEST=Check on F411 that FIFO data is retrieved and correct.
Check on Smaug as well, with proper kernel the collect the FIFO:
- check that increasing sampling_frequency we are collecting
the FIFO less often
- check no frames are lost.
- check tap/lift interrupts are working
- if latency is less than 100ms, check we are collecting much faster.
