Some Yoga laptops with 1 accelerometer in the display and 1 in the base, use an ACPI HID of DUAL250E instead of BOSC0200.
Set the iio-device's label for DUAL250E devices to a value indicating which sensor is which, mirroring how we do this for BOSC0200 dual sensor devices.
Note the DUAL250E fwnode unfortunately does not include a mount-matrix.
