dmaengine: cppi41: Fix an Oops happening in cppi41_dma_probe()
This fix an Oops happening on all platforms using the old dt bindings
(all platforms but da8xx).
This update cppi41_dma_probe() to use the index variable which is
required to keep compatibility between old and new dt bindings.
Fixes: 8e3ba95f4190 ("dmaengine: cppi41: use managed functions devm_*()")
