ASoC: omap-dmic: Do not use platform_get_resource_byname() for DMA
The DMA resource no longer available via this API when booting with DT. DMIC 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.
