Add a DMA engine driver for the TI EDMA controller. This driver is implemented as a wrapper around the existing DaVinci private DMA implementation. This approach allows for incremental conversion of each peripheral driver to the DMA engine API. The EDMA driver supports slave transfers but does not yet support cyclic transfers.
