commit 74a53a959028e5f28e3c0e9445a876e5c8da147c upstream.
After commit 7a3605bef878 ("iio: sx9310: Support ACPI property") we
started using the 'indio_dev->dev' to extract device properties for
various register settings in sx9310_get_default_reg(). This broke DT
based systems because dev_fwnode() used in the device_property*() APIs
can't find an 'of_node'. That's because the 'indio_dev->dev.of_node'
pointer isn't set until iio_device_register() is called. Set the pointer
earlier, next to where the ACPI companion is set, so that the device
property APIs work on DT systems.
