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 b36f09c3 ("dmaengine: Add transfer termination synchronization support")
