dmaengine: cirrus: Convert to DT for Cirrus EP93xx
Convert Cirrus EP93xx DMA to device tree usage:
- add OF ID match table with data
- add of_probe for device tree
- add xlate for m2m/m2p
- drop subsys_initcall code
- drop platform probe
- drop platform structs usage
>From now on it only supports device tree probing.
