[PATCH v4 07/14] dmaengine: add dma_request_slave_channel_compat()

Adds a dma_request_slave_channel_compat() wrapper which accepts both the arguments from dma_request_channel() and dma_request_slave_channel(). Based on whether the driver is instantiated via DT, the appropriate channel request call will be made. This allows for a much cleaner migration of drivers
