> Convert dmaengine channel requests to use
> dma_request_slave_channel_compat(). This supports the DT case of
> platforms requiring channel selection from either the OMAP DMA or
> the EDMA engine. AM33xx only boots from DT and is the only user
> implementing EDMA so in the !DT case we can default to the OMAP DMA
> filter.
