LSM6: Follow ODR change procedure from application notes
There are a few ways the current driver differs from the application
notes for the LSM6DS3, notably:
- FIFO disable is done before any ODR registers are set
- FIFO ODR is set before any FIFO decimations
BUG=b:122912601
BRANCH=octopus
TEST=used "ectool" to change ODR values on phaser360, ensured
"accelinfo on" output looked sane with the exception of points which
will be discarded next CL
