with the API implementation, this series implements the backend
device_slave_sg_caps() in the EDMA DMA Engine driver and converts the
davinci_mmc driver to use dma_get_slave_sg_caps() to replace hardcoded

This is tested on the AM1808-EVM.

The maximum size of an SG segment is limited by the addr_width
and maxburst of a given transfer request. These values are
provided by the client driver and used to calculate and return
the maximum segment length.

Replace the hardcoded values used to set max_segs/max_seg_size with
a dma_get_slave_sg_caps() query to the dmaengine driver.

that the given channel can handle.
