The IIO DMA buffer is a DMA buffer implementation. As such it should
include buffer_impl.h rather than buffer.h.

The include to buffer.h in buffer-dma.h should be buffer_impl.h so it has
access to the struct iio_buffer definition. The code currently only works
because all places that use buffer-dma.h include buffer_impl.h before it.

The include to buffer.h in industrialio-buffer-dma.c  can be removed since
those file does not reference any of buffer consumer functions.

Changes since v1:
	* Don't remove buffer.h include in buffer-dma.h since it is needed
	  after all.

Applied to the togreg branch of iio.git and pushed out as testing for the
autobuilders to play with it.
