jacuzzi: unmux pins away from emmc once we want to talk to sensors
Muxing the spi peripheral to both the emmc and bmi160 is probably not a good
idea, I'm pretty sure that creates an internal short between the emmc and
sensor pins. Disconnect them away from emmc before attempting to use them
for bmi160.
BUG=b/144892889
TEST=boot juniper, see sensor init ok
TEST=emmc still works
BRANCH=kukui
