rambi: fix two bugs with accelerometer driver Two bugs are: - Need to grab the I2C port mutex before performing i2cxfer. - Added sending software reset command to accelerometers on init. This is necessary because the accelerometers can be powered through an EC reboot, and it's important we restore them to a known state. BUG=none BRANCH=rambi TEST=Manually set accelerometer setting, rebooted, manually read that setting and verified it was restored to default.
