This patch adds support for ColdFire mcf5441x-family edma module.

The ColdFire edma module is slightly different from fsl-edma, so a new driver is added. But most of the code is common between fsl-edma and mcf-edma so it has been collected into a separate common module fsl-edma-common (patch 1/3).

So this revision fixed the issue we had seen with the previous version? Do we know what it was exactly?
