Thomas Gleixner b6205c3901 dmaengine: edma: Sanitize residue reporting
The residue reporting in edma_tx_status() is just broken. It blindly
walks the psets and recalculates the lenght of the transfer from the
hardware parameters. For cyclic transfers it adds the link pset, which
results in interestingly large residues. For non-cyclic it adds the
dummy pset, which is stupid as well.

Aside of that it's silly to walk through the pset params when the per
descriptor residue is known at the point of creating it.

Store the information in edma_desc and use it.
