volteer: Add board config for BMI260

Add board config of volteer for supportting BMI260.

BRANCH=None
BUG=b:146144827
TEST=make -j4 BOARD=volteer \
     && flash_ec --image build/volteer/ec.bin --board volteer
     Then, check sensor data is available on DUT by ectool motionsense.
TEST=make buildall -j
TEST=tast run ${IP} hardware.SensorRing
