Make use of the devm_add_action_or_reset() to register a custom devm_
release hook. This is required to turn off the IRQs before calling
dma_async_device_unregister().

Furthermore it removes the last goto error handling within probe() and
trims the remove().

Make use of disable_irq() and let the devm-irq do the job to free the
IRQ, because the only purpose of using devm_free_irq() was to disable
the IRQ before calling dma_async_device_unregister().
