driver: bmi160: Fix bugs found testing SPI
SPI being much faster, need to add right sleep to wait for
sensor to change state from suspend.
Set the ODR before the range, an issue I did not have with i2c.
Fix test used when FIFO is disabled.
BRANCH=smaug
BUG=chrome-os-partner:42304
TEST=Check sensors are coming and rate/range are correctly set.
