board: eve: Do not set accelerometer ODR beyond 200Hz
When ODR is set above 200Hz, the EC can not keep up with the
accelerometer, causing deadlock.
ODR was set at 400Hz for double tap detection. However, that high
frequency is only needed for LSM6DS0 where tap detection is done in
software (samus). 200Hz is good enough when tap detection is done in
hardware.
BUG=b:112672627
BRANCH=eve
TEST=Check eve is done dead locking at boot.
Check double tap still works.
