Nuno Sá 3db847df99 iio: buffer-dmaengine: enable .get_dma_dev() 
Wire up the .get_dma_dev() callback to use the DMA buffer infrastructure's
implementation. This ensures that DMABUF operations use the correct DMA
device for mapping, which is essential for proper operation on systems
where memory is mapped above the 32-bit range.

Without this callback, the core would fall back to using the IIO device's
parent, which may not have the appropriate DMA mask configuration for
high memory access.
