socfpga uses mgr->dev for debug prints, there should be consistency
here, so standardize on that. The only other use was for dma
which can be replaced with mgr->dev.parent.

Hi Jason,

this one could be independent of the other patches, this is cleanup and
could be merged before the rest (that's still in discussion) if you pull it out.

As I said in the cover letter, several of the patches are just fixes
and can be applied, but they are all linked by patch context so are
presented as a series.

Lets get as many reviewed as possible and then I can repost them in a
different order if necessary.

The first 5 are all straigtfoward and should be no problem to get
ackd. We've talked about the sanity check patch enough, lets just go
ahead with it now.
