ASoC: omap-mcpdm: Do not use platform_get_resource_byname() for DMA 

The DMA resource no longer available via this API when booting with DT.
McPDM is only available on OMAP4/5 and both can boot with DT only.
Set the dma_data.filter_data to the DMA name which will be used by omap-pcm
to request the DMA channel.
