dma: mv_xor: Flush descriptors before activating a channel
commit 5a9a55bf9157d3490b0c8c4c81d4708602c26e07 upstream.
We need to use writel() instead of writel_relaxed() when starting
a channel, to ensure all the descriptors have been flushed before
the activation.
While at it, remove the unneeded read-modify-write and make the
code simpler.
