PATCH v3 1/4 dmaengine: fsl-edma: add config and makefile changes for mcf-edma

This patch adds Kconfig and makefile changes to add ColdFire mcf5441x family edma support.
A new fsl-edma-common module has been added, to collect common code to fsl-edma.

---
Changes for v2:
- patch splitted into 4
- add fsl-edma-common

Changes for v3:
- remove Kconfig FSL_EDMA_COMMON and set fsl-edma-common.o as additional object entry where needed.
