iio: buffer-dma: add iio_dmaengine_buffer_setup()
This brings the DMA buffer API more in line with what we have in the
triggered buffer. There's no need of having both
devm_iio_dmaengine_buffer_setup() and devm_iio_dmaengine_buffer_alloc().
Hence we introduce the new iio_dmaengine_buffer_setup() that together
with devm_iio_dmaengine_buffer_setup() should be all we need.
Note that as part of this change iio_dmaengine_buffer_alloc() is again
static and the axi-adc was updated accordingly.
