Subject: [PATCH 3/5] dmaengine: mv_xor_v2: convert callback to helper function

From: Hanna Hawa <hannah@...vell.com>

This is in preperation of moving to a callback that provides results to the
callback for the transaction. The conversion will maintain current behavior
and the driver must convert to new callback mechanism at a later time in
order to receive results.
