dmaengine: fsl-edma: add ColdFire mcf5441x edma support
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).
