Yep. See chapter 8.2. Isn't enough proof? Or you believe in two
accelerometers with off-by-one conflicting address on a cheap laptop
with left unused two magnetometers on the same time?
And we have a driver for magnetometer separately.
So, it looks like we need to move ACPI ID to a new "kinda I2C mfd" IIO
driver under drivers/iio/imu/bmc150_i2c.c
