Robin Gong af802728e4 dmaengine: fsl-edma: add drvdata for fsl-edma
There are some differences between vf610 and next i.mx7ulp. Put such
differences into static driver data for distinguishing easily at
driver level. Change mcf-edma accordingly.

Laurentiu Tudor 0fa89f972d dmaengine: fsl-edma: dma map slave device address
This mapping needs to be created in order for slave dma transfers
to work on systems with SMMU. The implementation mostly mimics the
one in pl330 dma driver, authored by Robin Murphy.

Angelo Dureghello e7a3ff92ea 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).
