spi: spi-pxa2xx: remove legacy PXA DMA bits

Generic DMA support was already implemented by commit cd7bed00
("spi/pxa2xx: break out the private DMA API usage into a separate
file") which moved all the legacy PXA DMA implementation code into
its own file.

With generic DMA available for PXA, we can now just trash this
file.

ata: pdata_pxa: migrate over to dmaengine usage

This patch is compile-tested only, but the migration was actually
straight-forward.

ASoC: pxa: pxa-ssp: add DT bindings

This patch contains a cruel hack for looking up the the DMA request
number. The problem here is that the implementation as it stands will
allocate the DMA channel from the user of the ssp port, and hence we
cannot allocate a real channel here.

ASoC: pxa: use snd_dmaengine_dai_dma_data

Use snd_dmaengine_dai_dma_data for passing the dma parameters from
clients to the pxa pcm lib. This does no functional change, it's just an
intermedia step to migrate the pxa bits over to dmaengine.

The calculation of dcmd is a transition hack which will be removed again
in a later patch. It's just there to make the transition more readable.

ASoC: pxa: pxa-ssp: set dma filter data from startup hook

With the new dmaengine implementation, the filter_data parameter has
to be set earlier, from pxa_ssp_startup().

ASoC: pxa: add DT bindings for pxa2xx-pcm

The bindings do not carry any resources, as the module only registers
the ASoC platform driver.

ASoC: pxa: pxa-pcm-lib: switch over to snd-soc-dmaengine-pcm

This patch removes the old PXA DMA API usage and switches over to
generic functions provided by snd-soc-dmaengine-pcm.

More cleanups may be done on top of this, and some function stubs can
now be removed completetly. However, the intention here was to keep
the transition as small as possible.
