delbin: gyro sensor add 2nd source icm-40608

gyro sensor add 2nd source icm-40608

BUG=b:192990527
BRANCH=volteer
TEST=make BOARD=delbin
1. Set CBI SSFC 0x2 and using command
   "watch ectool motionsense lid_angle" for sensor icm-40608.
2. Using command "watch ectool motionsense lid_angle" for BMI260.
