This is v5 of my series to teach the pdma driver more required functions.
In contrast to v4, it has yet again grown by one more patch (2/5),
which removes code that clears DCMD_ENDIRQEN at the end of the pending
chain. We want to leave of the DCMD_ENDIRQEN intact in order to
identify where a transaction ends.
Thanks to Xiang Wang and Andy Shevchenko for their reviews.
