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 to the dmaengine DT API as platforms continue to be mixed between those that boot using DT and those that do not.
