Subject: [PATCH] iio:proximity:sx_common: Fix device property parsing on DT
systems

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.
