This patch series enables adds support for dma driver model and to adopt driver model. This has been tested on am437x-sk evm (logs [1]). also pushed a branch for testing [2]

changes from v2->v3: * Simplified device find from uclass_find_first_device() and device_probe() to uclass_first_device() so that all dma devices auto probes. * Changed ENODEV to EPROTONOSUPPORT which is appropriate here * Added documentation for return values
changes from initial->v2: * changed config_dm_dma to config_dma. * removed un-wanted enums. * added dma_get_device(). * removed post_bind in uclass driver and added device_probe in dma_get_device()
