iio: Add dev_to_iio_dev() helper function
This patch adds a helper function for retriving a iio_dev struct from a device struct. Currently we open-code this in two different ways. One is using dev_get_drvdata on the device and the other is using container_of. The new helper function uses the container_of solution as it creates slightly smaller code and also will eventually free up the drvdata pointer for usage by invidual drivers.
