[PATCH 2/2] iio: light: vcnl4000: Incorporate iio_device with PM runtime

["Mårten Lindahl" <marten.lindahl@axis.com>]

When the vcnl4000 device registers the iio_device, the iio_device
creates basic sysfs power/attribute nodes, but PM runtime is only
enabled for the vcnl4000 device and not for the child iio_device.

A result of this is that the iio_device sysfs power attributes is marked
as 'unsupported' and can not be used for control or monitoring of the
vcnl4000 device.

To fix this the iio_device should be incorporated with the vcnl4000
device by enabling runtime PM for it.
