staging:iio: Add ability to allocate private data space to iio_allocate_device 

Suggested by Arnd Bergmann.  Note this will break ALL drivers that
are out of mainline.  The fix is trivial change of
iio_allocate_device() -> iio_allocate_device(0)
Sorry if this causes issues for any one!

V2: Include new drivers in the update

@ -8,7 +8,7 @@ The crucial structure for device drivers in iio is iio_dev.
First allocate one using:
struct iio_dev *indio_dev = iio_allocate_device();
struct iio_dev *indio_dev = iio_allocate_device(0);
Then fill in the following:
