serial: imx: Replace dmaengine old API
dmaengine_terminate_all() is deprecated and should be replaced by
dmaengine_terminate_sync() in non-atomic context or dmaengine_terminate_async()
with dmaengine_synchronize().
See commit b36f09c3c441 ("dmaengine: Add transfer termination synchronization support")
