ASoC: omap: sdma-pcm: Correction for the include files
The sdma-pcm does not need any information from omap-dma.h, it only needs
to include the omap-dmaengine.h - for the omap_dma_filter_fn, but that
might not be needed at all as OMAP1 was converted to dma_slave_map, but
I can not test OMAP1.

Add the linux/device.h include as well for devm_kzalloc()

ASoC: omap: Introduce the generic_dmaengine_pcm based sdma-pcm
With the generic dmaengine_pcm support the omap-cpm can be replaced with a
much smaller wrapper.

CPU DAI drivers can use the:
int sdma_pcm_platform_register(struct device *dev,
			       char *txdmachan, char *rxdmachan);

To register the platform driver, txdmachan/rxdmachan is only needed to be
provided if the DMA channel names are not standard tx/rx, like in case of
McPDM, or the DAI is only capable of one audio direction (DMIC, HDMI).

This patch only introduces the source file and changes to the
Kconfig/Makefile, but does not change any of the DAI drivers to use it.
