[PATCH v1 1/3] iio: magnetometer: yamaha-yas530: Get rid of i2c_client_get_device_id()

[Andy Shevchenko]

Instead of relying on the name from ID table, which might be ambiguous
in some cases, use explicit product label in the driver data. With that
being done, get rid of i2c_client_get_device_id() call.
