David Lechner a05dc8b4d4 iio: buffer-dmaengine: document iio_dmaengine_buffer_setup_ext ...

The iio_dmaengine_buffer_setup_ext() function is public and should be
documented. Also, while touching this, fix the description of @dev in
related functions. @dev does not strictly have to be the parent of the
IIO device. It is only passed to dma_request_chan() so strictly
speaking, it can be any device that is a valid DMA channel consumer.
