dmaengine: at_xdmac: Use pm_runtime_put_noidle() with many usage_counts 

We're holding more than one Runtime PM usage_counts in
at_xdmac_device_terminate_all(). This makes pm_runtime_mark_last_busy()
redundant and pm_runtime_put_autosuspend() misleading. Drop
pm_runtime_mark_last_busy() and use pm_runtime_put_noidle() to decrement
the usage_count, except in the case it may be the last.
